Either one or the other can be worse based upon how it's drawn. I don't like pony plot and never will. If others enjoy drawing plot or whatever, that's fine by me. I just don't like it because i don't, period. I slap tits on my OCs all the time, ranging from big to small. I've also done fanart of Milky Way after i drew this image. If someone was forcing me to draw something like this, then I'd refuse it regardless if i'd get money or not. Besides, i have a ToS for anyone to see.
I don't understand what you're trying to do at this point.
I don't like drawing pony butts and don't like them if they're supposed to be showing them off to the viewer in a sexy tone. It's a personal preference and it'll stay that way.
Her upper body, and her lower body look like they're from two separate pictures, it makes it look like she broke her back. Her upper body needs to be facing the way her lower body is facing moreso (or vice versa) for it to stop looking so broken.
I used a NSFW pic as a reference for this pose since that's what the customer wanted. I showed him the picture and he wanted that specific pose. I never drew this pose which is why i used a NSFW pic as a ref since i couldn't find a SFW image with a pose like this.

End of discussion.
I think I got a nose bleed... Thank you for making this!
