You have a lot of great pieces here, and I'm excited to see the effects you're exploring.
If you could bring the top Will Smith down and left a bit, that might help tighten the composition and give you more options for your title treatment. (That creates a blank space next to his shoulder, but maybe there's a good piece of scenery or special effects for up there.)
Otherwise, I pretty much agree with the guys here that the two things holding this cover back from greatness are the font and color.
The font is a little too fat and bouncy, and the shading effect highlights that further, making it look friendly. Something sharper -- either sharp edges or a sharp metal texture or just a sharp flat color -- could help.
For the coloring, I think your 13 Hours, Matrix, and Sully covers are all perfect examples of great dark color palettes. The colors on this one might work with a lighter background, instead of the reddish brown. Or, you could simplify the color palette even further (not necessarily gold, but this is just an example):
