Not so sure about the beautiful, but meh. Definitely a disaster though, I'm getting worse, Please C&C....

The abstracts are cool, though the thing over the girl's eyes doesn't fit the flow, and seems strange. For the second two, the background colours don't really to match her lips and coat. Apart from that, they're all great!

Hmm......I disagree with Tea on the first one.

The entire left side is pretty much spot on. I don't have any suggestions for improving it.

The right side, however, lets it down. Then continued background design just doesn't seem to work for me for some reason, I don't quite know why yet. Rethink the right side of the sig, maybe throw in some smudging and more depth etc.
