To be fully honest, I think if you did NSFW art, it would come out pretty good. But I think you're one of those artists who can still do art without the use of erotica and still be fucking awesome like you already are.

Others like


and other brony artists do pony art without NSFW work and still are awesome. You'd be no different.

However I am one of those people who... actually Grievous says it perfectly well.
"YAY because DRAW WHATEVER the FUCK you WANT "

So in short, I voted for Neigh, but in the end it is really all your decision. But personally, I stay you should avoid porn and true pony NSFW stuff. Those types always make the artist look very typical. My personal recommendation is to stick to Anthro/Humanized Erotica. And yes, there's a difference between porn and erotica... BIG DIFFERENCE.

But like I said, in the end it's your choice... sorry for rambling on for so long. Just trying to give advice and wisdom when I can.
