Good work!
I really like this piece. It really is pretty good driving the whole mood of being a little fearful and as the title says self conscious. I enjoyed the background to where it seems everything seems to be coming in one the main character as if the whole world is judging her. I really love the blues and purples and they really mesh great together.
As for the main character, she is well drawn and does show some sort of apprehension, though it might have been better to have her in some other more prone position to make it seem she is more vulnerable. But all in all, this is a well done piece. Good work!
