The pictures are adorable. I love it!
However, I personally think the text on the banner in your signature could have been pretty'd up a bit more. o3o
But hey! It's not like it looks bad.
Everything's well organised, the art is freaking awesome, and I'm really glad you didn't use a white font for Froakie. xDDD;;
(But adding a stroke to the font would have fixed that, alternatively. o3o)
In terms of the avatar, there's not much to say. It's cute, haha.
They both work well together. It's a good theme!
7/10!
