Wow, OP you're super talented! I'd like to put one up of my wife. If you would be so inspired to try to draw her, that'd be awesome! If not, that's cool too, you've got a ton of requests on here afterall. However, if you do pick her, I don't mind waiting a while.
As a small request, you did one of the guy with his hand up to his face and you used some fun colors. Feel free to use some colors with this one too if you're so inspired. My wife loves pink/purple, but our wedding colors were gray, light blue/teal, and white. But hey, you're the artist here so you make the call of course. If black and white is best, you're the boss!
