Ok, time for me to finally make my opinion. If I offend anyone during this post, then I'm sorry, but I have to say this for the better.
You guys suck at making mixes.
I'm sorry, but it's the truth. You simply copy and paste things and don't edit them. Then you submit it and call it a mix. Bah. You don't recolor the pokemon at all. All you do is take pokemon and slap them together. You leave stray pixels laying around in the mix so it looks sloppy. You don't fix the outline or make the pokemon's hands, feet, head, etc look attached.
And don't tell me you tried. It's hard to tell that you did, IF you did.
I have found a sprite tutorial made by Shimitaro from www.serebiiforums.com. This is a lot more detailed than what you guys post.
