Thank you everybody !
I had never customized any toys before. After this pony I customized a Vintage LPS Pony for a swap on another forum, but since my partner hasn't received it yet I can't post pictures.
Actually, I don't like G2s like most of you !
I thought I would use a G2 since this was my first custom and I didn't know how it would turn out, I didn't wan't to "waste" a G1 on this !
