Hmm, I like this one, very elegant and simple. Excellent choice of effects. However, I feel as though the lighting could be better and the depth you incorporated around his shirt doesn't make much sense as both the effects in front and behind him are clear view. Although some of the bubbles help, this doesn't seem to have a sense of flow either and the text looks overly opaque.
i have to agree with auburn about the flow, lighting, and text, but the i feel that the depth is very good. While the blurring on the shirt messes me up, the bubble placement is good. The bubbles in the farthest plane (in front of guy) are less opaque. All in all the bubbles dont really have a theme or give flow, but they look good anyways haha. Just noticed that the bubbles have light in the middle of them, which is kind of distracting but not that bad. Good sig man
