its not bad. you gotta make riku stand out moree. shouldve had a blur or something behind him. And it's too monotone, work on that. Otherwise gj.
It's not that bad, mate. For this particular stock though, definitely make it black & white. :P Since the original stock is black and white, it would compliment much easier. Now as for effect's, it needs more. More foreground effects, that is. Get some C4D's that are close to the stock, and find some texture for them. Or you can just add C4D's, put them on a layer mode and then put a texture over that on another layer mode. There's many ways. lol The text could use work. Move it closer to the stock and make the font a solid sans serif font. Like Arial or Trebuchet. Incorporate it into the sig more, blend it, etc.. Also, increase the contrast a pinch, increase black and white difference (brightness) a little, and bring out Riku. Otherwise it looks somewhat nice. Far from being complete, though. :P
