I find the first piece very interesting. Did you glue a piece of white paper onto the more off white one? I think that sort of collage look would make the coolest wrapping paper and/or wall paper. It kind of reminds me of the old western/buckaroo themed fabrics of the 1940's and 50's.
I think you have definite talent. Did you not enjoy drawing them? Well?
So, get in gear!
