-all text is too big.
-Pokéname is too low
-HP could be at the right place, but possibly too high
-Razor Leaf is overpowered (but, if you wanted to have fun, then it's ok)
-text for Headbutt is wrong. It should be:
flip a coin. if heads, your opponent can't attack during your next turn. (sth like that; i'm not completely sure at the moment). but I can assure you that yours is wrong.
-it's Defending Pokémon, not defending pokemon
-energies are not centered with the circles in the background
-you can see white dots around energies, which makes it look bad. (also, the image of Bulbasaur- the white edge is visible)
that's all I could think of.
