I give you a 7 because i think that after seeing what you showed us int he forums this has turned out very good!
I noticed a few molding lines on the power fist and the gun ammo box but other than its looks great!
I think your next step should be working on your whites, try using a light gray as white and using your bold white as a higlight as you did with your ultramarine blue.
All in all great job, and keep it up!
