The art looks fine. I’m just more curious what the context behind the picture is. Like is she able to breathe underwater, or is her ability to hold her breath better than Spike’s?

As everyone knows, horses can breathe underwater.

Oh it is? I hope you’ll like the pic I still owe you, Because as you can see, I don’t draw the perfect drawings so maybe you should ask for a refund.

@Gyroido  
Even yours

@Background Pony #5620  
Yours is even more so.

Your comment is so unnecessary.

That waist on rarity is so uncomfortable to me. It looks like as soon as she steps back on to dry land her spine is going to break.
