Cover art for "Harmony's New Heroes" FIMfic.

[BrawnyCharger 511]

I've went and made a cover image for my FIMfic, "Harmony's New Heroes" 

I made it in Gimp. 

I don't own the MLP font, images of the ponies, villains, or elements. 

There are two different versions.

Version 1: For those who haven't read it yet.

Version 2: for those who have read the first 2 chapters

 

Spoiler

 

Which one should I use on Fanfiction and FIMfiction?

Is it safe to use these for cover art and would I have to get permission anywhere before I use it?

And what did you think of the pieces themselves?
