Ah, let's see once more...
I've gotta say, some of these look
really cool while others, well, don't.
I could classify Mudkip, Manectric and some others as really good, while Blaziken, Gallade and Armaldo are the worst.
Blaziken's face needs to be redone, I'm sorry, it somehow looks like a bowling ball with a splitted dildo on it >.< Anyway, Gallade's face could be fixed by retouching on the shading on the head.
Armaldo might be more difficult to "fix". I guess he just isn't suited to be fused with Lucario (he makes an excellent Salamence partner though
). Anyway, I would suggest NOT touching the face's shape to Armaldo's, as that screwed it up mostly. Just empty the lucario face and fill it with Armaldo patterns. Same goes for the belly. I think that dropping the yellow in the belly would be a good idea, so it's only metal, you could use the "yellow armor" piece then at the place where knee turns to lower leg, and use the black "dots" as a sort of transmittor between lowe rleg and feet instead. I think that'd mainly clean it up a bit. As the belly'd be made of armor, the knees of yellow, the legs of purple and the ankles of black stone, if you get my idea. No idea what to do with the arms though.
And, quite hoenstly, I think you need to widen your horizon. Try fusing other stuff besides Lucario, it'll give you experience in seeing what fits and what doesn't, which actually is all you need to become succesful in your case. You're talented, got a good eye for colors and patterns but you need some experience when it comes to shapes.
Keep it up
