Did a paintover to try and work through what I think you could fo to improve the coloring. Only did the twink because he's cute and I like twinks. I'm still learning myself, so sorry if it looks bad.
I went in with the assumption that this image was supposed to be sexually provacative, since you mentioned making BL in the character thread. If that's not the case, then you can disregard a lot of what I'm about to say.
I think the square texture brush is holding you back, it makes your edges a lot rougher and less natural looking, which means that the flesh here doesn't really have the appearance of real, soft and supple flesh. Some of the shading on the green haired guy especially looks pretty rough, which takes away from the lewd appeal. I think it might help you to try using a round brush for your shading, and to pay special attention to your edges.
I think you also use too limited a range of hues in your skin, and that combined with the lack of saturation makes it look less lively. Adding more saturation to your skin shading to give the impression as if there's blood underneath can give make it look more lively and inviting. I'd recommend looking at some of ModeSeven's mini guides on the stuff.
Other than that I think you should work on hands, because your's aren't quite stylized or realistic, and I get the impression you struggle with them. I think the blocky style doesn't really suit these designs when the characters have softer looking faces.
Also the dicks need more love. If you're drawing BL you need to give the dicks some love, that's the most important element right there. Please don't just draw them as limp blobs, give them more attention and detail. Your audience is gonna be here to see your boys butt fucking each other, so please put extra care and attention into their equipment. It's the only ethical thing to do.
