Re: The string lines picture thingy. That is the most MESSED UP assignment I have ever heard of, I think. Your teacher is cruel. The whole thing just conjures up images of glue-caked fingers and imperfectly aligned bits of string...you did well with it though.
I like your monochromatic piece. I always make that same mistake with the words...you assume they'll "pop" because of the white spacing, but instead they end up just blending in. Frustrating.
