Hello,

1. The lens flare in the middle although I can see what you are doing with it I think it would benefit off of it being removed.
2. The green and apple text looks fine but for some reason the gamer part just doesn't look like it is part of the image. Maybe try without the white glow.
3. The white splitters look nice and give the banner shape.
4. The minecraft render looks professional and the blur gives it extra edge.

1. Nothing really to be done to this. Looks like it does the job well and nothing really would improve it!
Good job!
If you ever need more feedback feel free to drop me a pm!
Hope you don't take offence to anything I say I try to be honest and sometime the truth hurts xD
Thanks,
Reuben
