I like it, more so than the other works you have showcased recently. The colors, the contrast, all fairly good. The background is a bit simple, and there is no discernible depth, but it looks good regardless.
The background looks a bit messy, there is no real structure in it (which does not mean that structure is always good, just in that case). It needs some more flow and I am not really a fan of those pale colors in such a signature. Anyhow the color compilation is good. ^.^ The text is too big, I would never place it over a signature. And the height of the canvas seems a bit small.
