Ninja Nathan's Sprites 'n Stuff.

THAT WAS RIDLEY!!!

Are you the 10-year-old kid, because this is the reason why we don't allow kids below 13 in forums.

Yes, the Ridley is pillowshaded, pillowshading is having the center of an object being the lightest and getting darker as it approaches the edges. That's what's happening here.

It's not that bad of a sprite, you just have to adjust the lighting to the front of him. It depends what you're going to use him for or what you want people to use him for. If it's for a shoot-em-up (galaga, raptor, dodon pachi, space invaders, etc), usually the lighting comes from in front of the sprite. You can also avoid pillowshading that way.

Good start, welcome to the forums. Read the rules and be a cool dude. B)
