The vertex edits look great, I love the Randi vertex and the gulimon/Your OC vertex.
One thing that I think you could imporve apon is your textures.I'm sure if you made them more detailed they would make your vertex look even better.
I know using parts from other textures in brawl (such as trophies and other characters)
help make the character look more detailed.
Let me know if you ever need help with textures as I'd love to help out
