These hacks are not good, I'm sorry. The only thing you seem to be doing is snatching other people's rigs and applying eye-blinding colors to the textures that were better left untouched. A lot of them are also recolors and straight visual downgrades from the original models.
I'd suggesting learning and adapting to Brawl's color scheme, as well as learning basic color theory among other things. You should also try learning how to paint your own textures online, as there are numerous guides for it in programs such as Gimp and Paint.NET, both of which are free. Lastly, take a look at the most downloaded mods and observe their textures; what techniques did the artist use to achieve these results, and how can I apply these techniques to my own work?
All of these tips will help you to become a better texturer, and a better artist in general. Keep working at it!
that's right the models are not my, but I made my own textures by Photoshop
