Those characters are improving vastly.
Hope to see you more often at the spartan camp! Don't be fooled its 'hardcore' title, it's really just an easygoing exercise.
Back on the characters - the green fairy really is good. Dizon covered some good points. About that lineart - Since it's a stylized challenge you can probably still have lineart, or even empathize it. I'm guessing it should still be functional, not just sketch leftovers. I know little of stylization, so just consider this food for thought ;P.
Either way, the hands show me you can do without the lines - they look great. On the contrary, there's an odd (looks like a seam line!) line on (her) right shoulder that's not needed. Hope I'm somehow driving my point home.
I can nag forever but I should not do so on this piece. Wonderful pose and strong image, and I think visible improvement.
Makeover looks a lot better. Perhaps you ran out of time though, blending and general rendering is more sloppy than the green fairy. Or do you have trouble with blending and combining the different colors? because the fairy piece was fairly monochromatic, and this one is very colourful. Or is it the realistic attempt? Probably just little time, but you be the judge. I do like the concept, especially her secondary weapon, good thinking.
Nice going on the amazon warrior - like the hair especially. You cought (dictionary sais this word is spelt wrong, but it's correct, right?) some very typical characteristics in this one.
Love those sketches, nice to see some early progress in there too.
That last cate blanchett caricature is an interesting one. It's a clear caricature, but seems to be without 'bad' intentions. You can still recognize the beautiful cate blanchett in there, just with exaggerations. Hope that makes sense. Lips seem viewed somewhat from below, rest of the piece is a sideview, looks a little odd. I think you can hide a little more saturated colours in there, like in the ref. To give her more life. Great ref by the way. Awaiting the final!
I'm a bit overdue... Hope this still serves some general purpose. I'll be right on your next update!
