There's a number of typos on the unupped card:
The card name says "fire
moster"
The passive ability says "
fier molten: fire
monter cannot be frozen.
The active ability says "
:
fier breath: deal 4 damage to the target.
As another note, the card says the art is by you, but the link you provide is to another game and has the following note at the bottom "©Pyxel Arts Digital Entertainment S.L. 2010. All rights reserved | Privacy Policy"
If you're part of the team at SpaniardBlend or otherwise have rights to the image I'll apologize, but I think you need to find another picture.
As to the card itself, it seems balanced but I think I've seen everything it does on previous card ideas. That isn't necessarily a bad thing, but it probably is going to make it a tough sell for some.
