wow not sure what to say...
Ya like every1 has already said, please save in PNG. It hurts to look at those. Also, dont go insulting people about their sprites, especially Blood Flood and Pokemole. They are not trying to insult you, only help you to improve on your spriting. I have made the mistake often of saving in JPG as well.
My words of advice:
1)Save in PNG! Can't stress this enough.
2)When doing fusions, recolor all the pieces to match one color scheme.
3)Keep practicing. Those sprites are good for a beginning spriter, but are very poor quality when compared to more experienced spriters.
4)Don't insult other people, especially calling them out about their art. I'm sorry to say, but you're sprites ARE
poor quality. There are very many people in this forum who can sprite circles around you.(This includes Blood Flood and Pokemole)
5)Always recolor the outlines of your sprites if you do any kind of recoloring.
6)And finally, NEVER use MS Paint's default colors. Get into the habit of creating your own colors, and soon you'll be on your way to making your own pallets!
Hope this has helped!
