Alright, for a start. the text you use does not fit in at all. You shouldn't have your whole tag on one scale of luminosity. Also, the focal point of you tag (the main/most important place of your tag which should be in focus and should be easy on the eye ) is the back of this guy. Try and work on that. Your tag oes have flow though. You have potential please carry on with GFX I would love to see you improve.
You've improved alot since i was here last you used to just get a render use the paint bucket maybe 1 or 2 brushes and a filter or 2 and a louzy text... keep going....
