Guess what friend, humans are v hard to draw aight? So this is pretty good actually. Okay man, so basically humans are VERY HARD TO VECTOR, and give lines for bcuz of detail. So its good to skip out on a lot of detail. But that doenst mean that you gotta leave out important shit like nose/eyes/mouth/ what ever. So what you can try and work on it maybe practice and get critiques on lineart first, practice with anatomy first. The important thing with humans is that you have to start feeling confident with drawing them realistically before you can develop rally a good or original style for them. So what I would do if I were you is practice mainly with semi-realism for a while, then every so often go back to see how you can develop your own style. I have some tuts I can send you to if you need and references.
Well, I'm gonna try to not be rude here. Here goes.
Well the hands are okay for now, tho they could get some more adjusting along with the arms, more "squareish" you could say. Also the head looks somewhat off from the rest of the body, you would edit the style of how you do heads to make it seem better. The tail is good however, it could have some more "fur" effects to it tho to make it seem better.
XD I pointed out a long of things I hope I didn't seem to rude about it, this is only my opinion I doubt I made a difference
