Since you are a newbie, I would say that the concept is good but the tag can be worked on and made better by a lot of different ways The blending of the render into the BG and the colors itself can use some touchups Maybe a few gradient maps and or color balance layers along with levels and curves As for the blending you can either try to use different brushes and smudge off Cena into the BG or just erase couple of parts As for the text, doing a stroke around the text is really old school, unless you want to go that way, but I would just say that once you are done type your text on a good side, (not that big font) and then apply image on a new layer and make that as a clipping mask and move around that layer till your text is visible this way you add effects to your name / text etc That's just my opinion Za
