It has no flow imo, Bg, text, and render effects are not good. I would scrap it and start from scratch. I don't mean this in a bad way, I'm pretty sure you could do better.
It's a love and hate thing. The empty space is meh but the render is nice. Plus since you set your own bar high it's pretty hard to top your work. Good job though.
This gets a 10 just because it's Granger. But yeah i love it, but the right arm makes it bad. just a few minor adjustment and this should be eye candy.
