Images of a pony sitting or standing on all fours should be a minimum of 800px in height, head-to-hoof. 1200px is preferred. Images of ponies standing on their hind legs or in an unusual pose should be proportional. Note that this refers to the resolution of the character itself - not the canvas.

Plus you missed the additional two legs she has

Well it’s not my image so I don’t need it. But you’ll make life easier for the guy who assembles the final collab image.
Sorry! I didn’t realize! I can resize it tomorrow if you need me to(?)
