I'm from Project Comment, please understand that my critiques are not meant to discourage nor offend you but rather help you keep making great artwork!I think you have a lot of room for improvement here, you're off to a great start though!The first thing that sticks out at me about this piece is his muscles. This is where practicing from non-animated sources will be incredibly helpful. His shoulders and pecks are well done but when you get to the abs they... they seem like he's just got long wavy chest hair as there isn't much definition to the abs and he seems to have quite large abs for his body type.Check out this picture here (It is not graphic unless you consider the top half of a man without a shirt graphic, he has pants on)He's got about the same body type but doesn't have such harsh lines where his abs are, just soft shading. That's all you really need on the body, just indications there are muscles there, not harsh lines. Save those for deep shadows, like under the pectoral muscles.(Which you did!)The second thing that stuck out to me first was his hips and crotch (not like you might think!) he's got rather flat tube legs and no hips. Despite the fact that it should seem like guys have no hips, they do, they're just super subtle!Check out this picture (it's just a lower shot fully clothed)See that gentle outward curve that tapers back in? That's how they should look. And the folds near the crotch and rest of the pants. Granted I think denim is a much stiffer material than the pants your character is wearing, it's still a good reference. His hips just don't go straight down but rather curve out just a bit. Now, this picture he has a shirt on but there is generally a 'v' shape on fitter guys where the legs, hips and torso meet that is visible as well, you showed it a little but it's a bit hard to see.A lot of things that would really help you get better and better is working on adding depth to your art. His shirt, his necklace and hands are all very flat. So much so that his necklace could be mistaken for a tattoo instead of something hanging around his neck. This is a really easy fix and just means extending the necklace chain/string a bit above where the neck is so it looks like it's looping around instead of just adhered to him. The shirt color too shouldn't just pop out and not connect to the back of the shirt but rather have a bit of dimension to it that shows it's not just a bit of cardboard. You did a great job with the sleeves of the shirt having rolls near the top and sticking out but not at the bottom of the shirt where it just lays flat on the pants.Great job with the hair though! It has depth, gives that nice spiky look and a decent amount of shading.I feel like his tail really should be tucked behind his staff, but it's not make or break on the piece, just something that would make more sense.And the only other thing I think you should work on is hands and body perspective. His left hand starts out well, but looks flat and it doesn't look like he's holding his staff at all but just resting his hand against it. This may be because he is lacking a thumb that should be visible when holding an object like it is. There's a lot of ways to add depth to hands, but it just mainly requires practice. As for perspective, that mainly requires looking at a lot of references, making sure that body parts don't come off looking too short or stubby when tucked behind the back and things of that nature. It's a hard thing to practice but when you get better at it, it really shows!I've glanced through your gallery and am seeing that you're improving each time so please keep up the good work!
