Here's what you do to improve it:
1. Recolor the whole sky to blue using the NSMBU Beach BG sky palette.
2.Get rid of the SMB3 pyramids and sand.
3.Paste the whole Layer-Cake Desert sand in(16 bits).
4.Move the Stone-eyed Heads in different positions.
5.Add some more Stone-eyed Heads.
6.Add all the Layer-Cake Desert clouds(also in 16 bits).
7.Add the Layer-Cake Desert melting ice cream(in 16 bits).
8.Add some Layercakes(at the end of the BG),as you can see in the first reference picture.(in 16 bits)
9.Should be resized to 2016x1000. You can use this blank spritesheet to put the background in(2016x1000):
11.No blurry pixels.
12.Everything must be in order.
13.Stone-Eyed heads should be like the ones Squishy Rex made.
I would really like your help, guys. Thank you very much.
