Comments for each one!
Hiya!
1. First off, lines are evil, but eh. Is it a dude and a chick or two chicks? I haven't seen the show/etc. Because if it's a dude and chick he looks like he has boobs. The lines are too strong and rounded for a guy. With the fingers on the sword with each finger that's further away it should be thinner than the one infront of it, just so you get some perspective and it doesnt look as flat. The heads are a little oddly shaped, his ear is too high up and back and her cheek needs to round out a bit more or at least go into the chin line smoother. Her straight arm needs a little more definition but overall that arm/hand is fairly good. Necks curve out on the downwards where they connect to the shoulders as apposed to where they connect to the head. His back arm is a bit akward behind him you should be able to see a bit of his hand near his leg unless his arm is pulled back which I guess it could be. Overall good form and shape.
2. More lines, ick. Lines don't need to be/shouldn't really be too strong on the nose unless it's an animal, usually a kitty or something with a muzzle anyway. Overall she's pretty good, a strange lookin girl but nice. Could say the shoulders are uneven but we'll blame that on the way she's standing since we can't see the body.
3. Wow, I feel sorry for her, she must get teased alot for those boobs.. haha. *cough* Anyway, kinda obvious those need to be more in proportion with each other. Her nose looks strane because you've got a front and side view mixed together, go either the pointy line or the straight one or two straight lines not a pointy and straight it just looks odd. Also it's a bit too high up, or more it doesn't extend far enough, a nose does not start and end between the eyes it goes lower than them.
4. I haven't watched Sonic X in ages, that kid irritates me. I think Tails is a bit too round headed for Tails, doesn't his cheek fluffness stick outside from his head? The flower/girl thing I like, the only thing would be her outstretched hand which I think is the wrong angle, not too sure though.. Also where her arm meets her armpit the line for her side should be over the one for her arm.. i think. The angle's a little off for me to be certain, it'd probably be more of a cosmetic thing.
5. Heads need to be rounded more, from what I can remember of these things they've got like circle heads.. I could be wrong though. The one of the left definately needs some more cheek under her half turned eye though. The one on the right, it's hand has the same issue as the dude with the sword in the first picture, you need to thin the fingers as they go back to give it perspective. Well as I know less of these characters than the general sonic ones I'll just say they're pretty good over all.
6. Is the first/last one's supposed to have no neck? That's the first thing to go 'what the?' Ok first one, the little girl would probably look less unsteady if both her legs where flat with feet on the ground, her body doesn't say she's really moving but her legs say she is. Middle girl, hand thing again though this time she starts with a small finger which should be the other way around. I like he though, maybe her boobs are a bit odd but eh. Last one, that neck just erks me though I can put it to character design so eh. Her legs are too thin but I don't think you really bothered with those too much just because they seem to be rather light. Overall nice picture but for the lines.
7. Last one! Awww.. cuteness! You need a bit more practice with hands but then most everyone does. I can't really critic too much on these they're all really cute and well done pretty much. The coat on the one in the bottom corner should probably split further down than it is, it gives her a bit of a bump in the front where it is just now.
Overall they're nice, draw more!
Oh, one thing though. I'm guessing you did these at school, yes? Get some loose leaf white paper and shove them into all your books/binder/whatever so you can scribble on that instead of the lined paper if you don't have a sketchbook thing that is you can take with you. My mum did it for me ages ago n it makes it much nicer to draw, unless of course you're scribbling in the borders of your work >> Just remember you're supposed to be doing school work and don't let the teachers see you scribbling more than working!
Hope the comments helped!
Happy hunting!
