So apparently according to this artist if you are a brony you cannot be on her page... I like the yellow used but the message is quite racist. She's also has them in Weaboo, FNAF 5 and Undertale Sans flavors. 

This one's a bit offensive... our artist is calling ponies "stupid". This gives me the impression that the artist is very immature even though being at the age of 20. yes 20. Also this is a mis-truth as ponies like Pinkie Pie shown in the stamp are quite skilled. Twilight Sparkle being a very cleaver pone and very good a problem solving. 

You have used LOL when not needing it. And don't tell me it's "ironic" 'cuz we can't tell

Attention's great that's why we post our art, i know, but saying you want it and making a stamp is a bit pretentious in the worst possible way. Just join some groups and stop making immature stamps. Also maybe it helps it you didn't make stamps excluding fandoms from your page. Just a thought.

Really, i thought you would have liked him. 

This is a piece of her non-stamp art.  I think your style would lend better to cubeecraft templates. Also you should think about using other colors for there outlines other than black, looking at MLP's G4 general art style for the lines they use a darker shade of the fill colour...

Who's "stupid now"...
