hehe, funny what you\'re doing with this Trepor.
BTW the body doesn\'t looks like that in real

Also, you should use a sharpen filter on your bow (you\'ll see it will fit better with the character who\'s lacking of antialiasing).
You should also consider shadows. Even if there are no shadows in the original sshot you can create some for characters and trepor. Will increase a lot realism.
You can also change the hue of the trepor to something with a bit more blue (an additional layer in overlay mode could be perfect)
Oh and I think you could also remove the outer glow you put on the bow and arrow
nice work!
Edit: here is how I see some improvement. Hope it help.
