I really like the colors in this one, though I feel like there is a lot of this signature I'm not actually seeing. The smudging looks awful IMO. It's very linear and covers like 80% of the signature. It doesn't look like much effort went into trying to blend the different colors and create a focal point. The render kind of just sits in a sea of random splotches of color. The other 20% of effects look good but they're too covered up, so I can't really say how I feel about them. Over all I'd say its far to chaotic. Next time try to tone down the smudging as well as work with different ways to balance the effects going on here.
