Drawing on I-Chat

I suppose it's a funny situation that I have at home because my family lives in California and I live in Portland.
My twin sister and I both drew together throughout our lives and therefore, I cannot get used to drawing without her feedback. Luckily, we both have a Mac and I-chat and are able to meet on there, scanning our roughs and paintings/comics back and forth to critique.
I find this invaluble because she's able to see what is wrong with my work immediately, as I am with hers, and because we are so used to each other, we are able to verbally (and sometimes not so verbally- we ARE twins) steer the other in the right direction.
Last night we went back and forth on how I might paint this next piece I have planned out on my watercolor paper. It's more complicated than some of my other paintings, which is good, but it also, if I do it right, should convey a "mood." I've been wanting to really build that in my paintings.

I have also decided, after being inspired by several comic books, to once again, do some black and white/ink work.
So it's nice to be back at the drawing board.
