NO. GIF. LOGOS.
GOD NO.

Sorry about that. But seriously, they are taking up too much of the user's attention, they are too distracting.

I really like Sharwul's logos.

If I may comment on some of them:

This one looks really nice, but I don't like the font. I'd recommend you choose a lighter, somewhat more static font.

This one's really nice too, as a logo, but my opinion is it doesn't quite fit the theme of TPT.

Better with any of these fonts?

That one looks nice.

The other too, in my opinion, still have too thick a font.

I made this with a picture from TPT:

And here is one with a thinner font:

None of the logos really reflect the actual powder toy though...

i really like that one
