I like it, but somehow it looks a little plain. It needs some lighting. It has very good flow, but needs more depth. I would suggest add some lighting at the bottom left where your text pattern is beginning. I also would suggest that you add some wireframes, as, imo, they would look good on this sig. If the canvs was a little bigger it would have been even more nice. I really like your pattren though, your signature has perfect flow. The only thing it lacks is depth and lighting, and needs some wireframes to make it look better. Goodluck ^^
