So, looking at it you've definitely made progress, but there's still a few bits I'd like to cover. Firstly, the lines. There's a LOT of lines you should be erasing. There are some styles where keeping lines works, in fact RCBC's style seems to keep some of the lines, but even if you were aiming for a style like that, there's still a lot of sketch lines you should've gotten rid of. My tip for this is just to draw lighter, and when you get the line right, draw over it until the line's solidly darkened. Another thing is proportions. While you are getting better, there's just a few things that look off to me. As Pink said, your hands are getting better, but they're still bent at non-human angles in parts, especially that pinky, and some seem far too long to even be long fingers, like the thumb actually being longer than the ring finger. The neck also seems a bit long, though, again, that could be due to the lines. It's hard to tell where the actual chin is. If it's where I THINK it is though, a little below the mouth (which is fine), the head seems disproportionate to the neck entirely. The neck is enormous compared to the rest of the body it looks like. Your ears are fine, better than mine anyways, which is honestly a good start. I can't even manage ears yet. Well, I probably COULD if I tried for a bit, but... I really don't want to try learning a new body part right now. Your hair looks good, actually. Can't see much issue with that, aside from the aforementioned lines. I can see you've added bone and muscle structure to the neck, which looks pretty good. Only thing I have left to add is that the torso seems to curve unnaturally. On clothing as loose as that, it would hang at almost a straight line, albeit with a few wrinkles, or the clothing waving due to force against it, like wind or something. Even if the clothes were tight, I'd say to just continue working on the torso structure a bit. You're making progress though, that much is evident. Oh, while I'm at it, the arm being held up. I don't know exactly how to phrase this, never was good with wording things, but the elbow joint of the sleeve, the uh... The line bit where it separates the joint, y'know that one that descends from the sleeve line downwards? It might do you good to make it a bit longer. At the moment I feel it just makes the two parts of the arm look disproportionate a bit, but that might just be me nitpicking.
ANYWAYS, art tips/ranting aside, I was meaning to ask. Do you think we could use this thread as just an art improvement posting thread in general? I've got some art I've been meaning to post somewhere to ask for advice, and this might be the perfect place to do it.
