Then you should at least give credit where credit is due, I'm sure Mode7 wouldn't like people using their graphics without it.
That's like spriting a pokemon to look exactly like Nintendo does, but then resizing it and saying it's yours.
Do you have a bigger version of your avatar? I want to use it in the Character Bios section of The Tempest if you do. I already have the small version of it, but it's just too small I think, so it doesn't look as good.
