Yes, cool pictures, too bad the hand and feet get a bit cut off.
FISH: I'd like to see it finished, though the negative space is kind of cool, but at least need her body complete.
MOOKIE: I'd like to see it larger but it looks nicely done.
COLBY: Nice, love her sultry face, looks like you tightened up her swimsuit top too, heh.

No feet though? Tsk tsk.
SIRKOWSKI: Entertaining take, heheh.
ROXX: Keep on practicing, its coming along. I like the mermaid take on it, maybe throw some splashing water by the rocks under her tail.
AMERICOMMANDO: Not drawing for a while is bad for your health. When I don't draw for a while it is painfull to start up again. Congrats on joining in on a jam. I like the style and shading and such but seems she has a few structural problems in the face and shoulders.
REG: Looks like those lines are scribbled in all the right places. Her head seems a bit small or something though. But can't really trust me on that cause I usually draw cartoon people with big heads.
RAUL: Thats kind of a cool eerie effect with the lighting and dark eyes.
CRITHON: Love that style. The subtle but effective chair highlights are great. I'm not into those colors personally though. Would love to see it done like that with a couple more vivid contrasting colors but that's just me.
BENJAMIN: Nothing wrong with that. You might shorten her torso a bit. But yeah, this is a good place for the practice.
CHRISTOPHER: Congrats on your first post. Looks good. Keep posting.
Here's my take, not as cool as I would have liked it to come out but I'll give a try at coloring it sometime here...
