the line art is awsome it almost looks like another series to tell u the true i don't like freezing that much.
more said i hate freezing but if were u who made series and the manga i would definitely watch it!
but the only thing i don't understand is why did u color it with a light red under her right arm?
not only that, but i don't know how u made the light effect(the shadows) some are right like in her left leg, but the rest i don't get it.
and in the glasses instead of using a darker skin color u could have used white (or is she blushing or something?).
Anyhow your color technique is fine, i can say u are better then me, (cause i don't know which program is cool to paint, but if u tell me the one that u use or know i would be appreciated), but i can still paint with other stuff thought
keep on the good work, ill do the same in order to improve my art. KD
