G4 My Little Pony collectors, check out this fake Pinkie Pie I found. Tell me what is the difference between this and the original?

I've never had any My Little Pony toys in my life, this is my first doll even though it's fake, but it looks a lot like the G4 toys!

Currently, G4 toys here in Brazil are very expensive, but the normal ones are, so the only option I had was to buy this fake, but it's actually pretty.

I'm thinking about customizing this doll for one of my characters?
