... I just idk... Its beginner quality at best... Like um, idk how to say this in a way that wont sound mean because thats not what im going for... it looks like you used photoshop for like 2 weeks.
I wont be as harsh as other people but Im pretty sure other people have told you enough. All Ill say is that there is alot of empty space; try some effects and blend it in. good job though..kiu
