Text should flow, and frankly at your skill level, start integrating effects/skill showing elements into the text also - the signature's quite nice though the text lowers the overall effect of the tag. Blending's not great, composition needs a lot of work (even if it's really complicated to make, atm it looks like an unblended c4d on render on bg stock, even though i know you can do better). Flow/colours could be a lil more adventurous too
