Alright. I like the Riolu edit.
That's not crit. It's a simple, one-liner comment that doesn't show what you like about it, and what can be improved.
Well, I like the Riolu edits also, mainly the dark one for the patterns that you used. But besides giving it claws and a bit of a hooked tail, there wasn't much changed about it. The Psychic one just has a ring and some aura around it.
I'm not saying these are bad, I'm saying that they're very simple for retypes. You need to completely redo some parts of the body, change things, add different colours, maybe even change the pose a little, and how the body parts are positioned.
The Sunflora, I don't even know what you fused with it, because it's just a recoloured Sunflora. To fuse, you must include other parts of the Pokemon. Like, the arms, or legs, or a tail, or maybe fuse both of the heads together. That's what a real fusion is.
The scratch is really cute, especially the eye, which I think was done rather well, but it's way too small. You can barely see the feet, or the detail of it because a small sprite leaves little room to give detail.
I do like the scratch sprite, I think that it was done rather smoothly, and the shading is decent for such a small sprite. Although I'd love to see a larger version of it.
