Pros:
Acceptable color scheme.
Cons:
Render isn't positioned properly.
No depth.
No focus.
Lack of eye-catching effects.
Border doesn't fit.
No proper lighting.
Overall:
You need to read up some tutorials on the different GFX techniques, such as the rule of thirds, lighting and depth. You have potential, and i can see that you have a certain image in mind, but you can't canvas it properly without first learning the basics.
I may sound harsh, but trust me, i was once where you were. Sugar-coated criticism isn't gonna help.
I will say though, you've done better than i did at my first GFX attempt.
