@GuttedBunny: Ok, I'm gonna preface this by saying that you may not agree with me, and I may come off as harsh, but really? This is just blunt truth from my own personal experiences.

I can relate. The whole 'my art sucks because X, Y, D, H, W are better and cheaper' (I offer commissions, so the price point is part of my own lack of self love). I think almost every artist can relate to that, actually. It's pretty common. It's human nature, from what I know, to look at thsoe that are better, to compare to those that we feel are better.

I'm not gonna say you have to stop doing that for two reasons: one, you'll never improve if you don't have a level you wish to achieve, and two, it's easier said than done to stop doing that. So I won't say it, I won't reccommend it. I don't believe that does any good anyway.

I will say this.
Test new things.

Literally.

For instance - if you specialise in digital art, pick up a pencil and paper. Give traditional a shot.
If you like to draw greyscale pencil, try throwing some colour on thee.
Pencil Crayons? Give watercolour pencils a shot, or just outright watercolours.

I know what it's like to have no drive to art (yes, it's a verb. Shhh). I've been there, I live there. It's no fun.
Sometimes, the best thing to do is to try something new, maybe that'll spark something.
Or just set yourself up and sit there with the pencil and paper (this trick really only works for traditional, sorry). By thatr point, it's usually a case of 'well, I'm here... might as well do SOMETHING since I prepped' or whatever. It can help too.

If you want to inprove your art quality, consider the following:
►Draw every day. I sucks, but even just drawing one face every day will make a difference for how you draw faces.
►Consider gesture drawings. Seriously. They can really help with the fluidity of the poses.
►If you need to, take a break. Go for a walk through a mall, a forest, whatever makes you happy.
►Possibly consider seeing if you can find an 'art group', if that would help. Even if just a skype//discord chat channel where it's a group of friends that are there for each other. If traditional, can be a group of people that meet up every week or something to just art together, to help keep everyone in gear, so to speak.
►Art books. I know this isn't the cheapest option, but consider art books. They can help with tips and tricks for how to go about drawing/colouring X thing that is giving you a hard time. You can find loads of tutorials online too for free~<3
►Youtube. I wish I was kidding. My art can improve by leaps and bounds in a 1 year or less period because I find loads of tips tricks and the like on youtube, in the speedpaints/timelapses and whatnot.
►Consider bases as a start. I used to constantly use bases because I knew my anatomy sucked, (It still does, let's be honest) but now that I have a feel from tracing the bases onto paper (they were digital, I wanted to draw on a piece of paper) I have a better grasp of where the breasts should be, or how wide the shoulders should be, etc.
►Try different mediums. Or programs. Seriously. I had never tried sculpey before, and I find I cannot draw pokemon or gryphons, but I can sculpt cute chibi versions. Who knows, that may make all the difference for you too.

Honestly, the best thing you can do, is first off sit back and weigh one thing.
Do you honestly want to draw, or do you feel like you are continuing to do so just because you feel obligated due to your history/whatever?
I mean, is there an honest interest in it still? Your thread title alone makes me wonder if that's the case. If you can answer that you want to draw the best thing to do really would be to just stick with it.

Oh, and find anime screenshots (if you want anime anatomy/style) and just copy the bodies/features that you have a hard time with.
I had a sketchbook filled with pages full of random hands, eyes, lips, faces, bodies, feet, etc when I was in highschool. Lol. I think it's part of what helped me get to where I am now.

Art is not easy. There are so many factors to consider, that all one really can do if they want to deal with that tide, is just try. Try and swim against it, keep practicing.
As you improve with your art, and are actually able to sit back and be like 'ok, I may not like the rest, but damn that hair looks good' (hair, eyes, hands, belt, etc.) the more you'll be able to just sit back and appreciate that YOU are the one who did it.

Oftentimes with some of my best work I'm here like 'holy crap. Did I draw that? I can't have... that's just... that can't be real', yet it's in my sketchbook, or recorded and I know I did it.
That's not as rare as one would think.
But Anyway, I've probably rambled enough and gone way off topic (I'm so bad for that, sorry!!) so if you can make sense of this mess, props to you. Lol.

Also, can I just say, I adore the oil pastel sample you've got in your shop? It's frikken fantastic. And the graphite example~<3
I love how stylised your stuff is~<33

All right, I'm done. Sorry to bore(?) and/or confuse ya.
