I think youre on the right track with the guy in the center, work on your facial proportions: mouth line/opening is 1/3rd down between nose and chin and that indentation under our lips is 1/2 down between nose and chin.
You have REALLY expressive different characters im jellin' hardcore over man

"my cheeks are warm!"

Could be used for a comic/comical image (as long as you avoid lulsrandom )

a few drawings from drawing II class. posted in chronological order. the first one is a guy we had to draw; shaded with charcoal, no line. had either 5 or 10 minutes, i can't remember which.

the second one here uses water-soluble pencils and pen. about ten minutes. my scanner scanned it in weird and the proportions read as kind of off.

the third one is one of the biggest things i've done, using just charcoal. it was too big to fit in the scanner i had so the bottom is cut off. 20 minute figure drawing. didn't want to smooth it.

I see really great potential here, I like the character in these but what really helped me in figure drawing was this page: http://www.dhfa.net/Artiststatement2.html

What program do I use to draw???
(edit: things with smooth lines.)

I really need one with smooth lines as well, however sai dont help me much. Diggin the eyes and vinyl hair on this one, i think you could make cool psychedelic art.

Up the the contrast on the right side of skull and maybe make the horn stick out more with some carefully placed darks?
also i would put some tiny pebbles or something scattered about to unify the piece and maybe strategically place them to push your 3x3 relationship further

faux graffiti

his name is Manny, and he only has one arm

graffitis colors seem really pixelarty to me, the colors dont seem to be unified or related too much, and i think it lacks good discerning contrast.
the lineart is fine, you just need some extra details in the face hands and clothing and lettering ( I would study some graffiti for good stylistic line thickness) The idea is really good, and i think it just looks off b/c of the low opacity with makes it seem too light to me.

Really good volumes on the guy, im gonna recommend you look the the links above and pull some figure studies as you already have a good understanding of volume and weight

Character design.

I think you should experiment with fall and spring colors, perhaps add a charm/ribbon/protruding element near the pit of her neck?
also i dont know why, but when i looked at this, this poster came to mind: http://www.madman.com.au/wallpapers/summ...1_1680.jpg
