Your lacking major blending when it comes to your focal. Your contrast is quite nice, but it seems too consistent through out the piece, which makes your lighting extremely poor.

Your effects seem okay, but adding some around the focal would create some better blending and also more of a 'wow' factor to this.

Your text could go and as well as that little green thing in the corner. I just caught that when I scrolled up and now it feels extremely distracting and out of place.

Good work, keep it up ^^!
