Alright, here goes.
As usual your background fits well with the piece.
Your blur/sharpen/focal is quite bad in this one, to be honest. What the hell is going on in here?
I don't know where to look. The shoulder looks way too sharp and so does the arm. The pointy thing on the shoulder is blurry, how is that possible? The front leg is also more blurry than the back leg and his weapon arm thingy is unclear. The head is also too sharp but that's because you blurred the rest so much.
I find the colours quite bland as well, it could've used a red or blue stream of light to spice it up.
It's... Messy.
To be honest it seems rushed.
You can do way better ;]
