Okey nothing really i would sugest just to clean the DEF file and get rid of the aditional text and codes you arent gona use on the next release like these:
;Z offset for drawing
;Adjust this value to move the ground level up/down in the screen.
;It's the position where the players stand at.
;Up - smaller, Down - larger
;***
and this:
[bG OutSide Earth]
type = anim
actionno = 0
start = -128, 0
delta = .8, .75
mask = 1 tile = 0,0 <<<<<<This
trans = none <<<<This
Just to keep it more organized and easy to understand.
Also could flip the shadow from yscale = -.1 to yscale = .1
shadow get slighty out of the mouth while -.1 besides make more sence since lightsource should be from the earth imo
