I know it, but the full-tilt rule 34, which I've also been known tho draw, is for galleries like Hentai-Foundry & FurAffinity. Mildly sexual straight-up suggestive? I suppose Rule 34 Lite. All the tongue action with only 10 calories!
I don't have any problem with you coloring it. Just put That " :icon(name goes here):" and my name will show up with a link to me - should keep anyone from going all "U STOLE THIS!" etc. comments or whatnot.
Sure, you have my go-ahead. Just make sure to credit the original to me and link - otherwise others might come down on you in some drama-tastic fashion. When you finish it, send me a link and I'll give it a like!
Although as time goes on, it feels like I merely yelled "First"! on the comments section to Rule 34. Probably wasn't even the first, though since this one is technically safe-for-work it got popular pretty quick.
That's one of the colors of my piece. Can't remember who did it, but I think it's one of the people nice enough to ask permission first. But I'm not sure of who's hosting it. A handful of artists have altered or adapted it, and a few cosplayers at conventions have... well, let's not even talk about that.
