massive updates! you've been watching naruto?(because of all the ninjas). I like the character designs. You still need to work more on proportions and draw shapes first before putting details on your characters. A 3-d shape for each body mass and limb.
girl on top looks pretty good. I can't see her feet planted on the ground though. And if the legs are in that position, you gotta have some hip slant. Leg holding the weight should push the hip up. Guy on the bottom needs darker lines to define his eyes, corneas (the round part) should be bigger too.
the pose in that last girl is looking great. she has decent wieght and balance.
note 1: the groin, it doesnt make a triangle between the legs. in the genital area thier is a small space. its doesnt meet up like this /\ kinda like this /-\
note 2: dont stop drawing it. u should go back after awhile a keep fleshing it out. that helps also wen ur having a creativity block. you first step should always consist of getting down the idea, no matter how sloppy or messy it is. the next step is refining u idea and finding the like work u like. then keep going back and touching this up.
note 3: like note 2, draw everything. i know i do that too, i get lazy and just dont finish. or mabey u see in professional art they dont finish thier drawing they just suggest stuff. thats ok wen done tastefully. but they always keep important things that help sell wat they drew. a few easy things... finish the hands up. they say a lot, even if u suck at them give em a shot. and do a bit more line work on the face. thats a huge part about doing a character design. if the face isnt working the rest probably wont either.
note 4: awsome work! good proportion. and ur lines are looking hellalot more confident.
and yes like penc, i like the fish shoes too! lol great imagination.
nice stuff. im gonna back away from criticing for now. there are some things u just gotta figure out urself. it will just be a hot and cold game for awhile. ur shading is looking good on that one. good stuff. keep posting.
oh yeah, forgot to mention this. When you shade, either use consistant hatchings or use the side of your pencil to get a consistant value. If there are a lot of stray marks, it'll look confusing. I think shading with the side of your pencil is the best way to go, it's quick and consistant(with the value).
