Nah, I think I'm pretty happy with them as they are. Canon ponies don't even have genitals, so it's pretty much up to the individual artist on how they want them to look.

Alright. And that is true. But giving one gender one set of genital designs, and the other another set of... or lack thereof, is kinda odd if you ask me. It's a bit like, having all your male ponies have feet instead of hooves xP

But ah well. Can't tell you how to draw, but generally tends to be a good idea to match the design of your characters. Though, I can recommend try drawing the opposite of what you do now. (ex: equine or even just human vulva, and/or human penis) Even if just for once. Had it a recommended technique by many artists in order to get better insight in how your art looks, as it gives a "from the other side" perspective, as it'd allowed you to see it as others might view your current style. Hopefully don't come off as pushy or anything like that, but can't tell how many times (50+) I've had people "dead set" on a view, change it after giving something new a shot. Our brains are actually surprisingly easy to re-adjust. And while I know the term is generally used in a bad manner, I can say I am a believer of the terms "you might not know you want it until after you try."

And geez, it's really hard to find that golden area of "friendly suggestion", not having to worry about tripping over to the "pushy/demanding" area...
