i like the expressions

That's not alll, I just bees the suggestions...

If you want to try something diferent, try this page, and try to draw the bodies.

i can help with a few things.
1. study human anatomy. just look at yourself in the mirror.
2. go get a drawing manikin. it'll really help you out to know what the proper proportions are. plus you can use them to practice new poses.

the arms are too short, the hands should be at around mid thigh.
you need to actually give them a wrist.
the arms are too bulky
give them a neck too

not trying to sound mean, just correcting you.

I agree with  drakoknight those are the same observations i have

*looks it over... zooms in, turns head about and looks over more closely* Hmmmmmmm... critique, eh? I'll take a shot at it... :oP

Well, considering my build (and how loose my sweater's sleeves can be), I wouldn't say the arms are too bulky, but they DO need to be about six squares longer (going by the scale of that graph paper), which, as already mentioned, would be about mid-thigh... ;o)

... also, purely optional, but my bad-habit posture occasionally fools people into thinking I have no neck... XoP

Thanks for making it; I like how it's coming along! :o)

*gets sucked back into assignments* ;;>.>

I would have to agree with with DrakoKnight also I guess.
The poses seem a bit stiff or something. Not sure how to quite describe it though.
Though everyone has their own style, just take your time and try to use real photos for reference to help you.

I actually observed the same things as  drakoknight said. That mannequin should be able to help a lot with the things he mentioned.
Also using photos as a reference would be really good too.

it took me ages to get the anatomy right.manikin is one way and a photo ref is good too.that site lord-mondragon mentioned looks like a good idea,i might try it myself as i have trouble with poses ect

The only advice I can really give you is to perhaps look at other people's artwork and see how they've drawn the poses, and maybe you could learn something from it. Other than that, I think it's a good idea to keep practicing and experimenting with different things.

it's gonna looks great when colored

You give it a good shot and that is all that matters.

Looks good buddy ^^ The only thing I could think of would be to make the arms just a little bit longer, and the eyes just a little bit lower. Good job!
