I would draw a sketch of what I imagine them to look like, but I'm not able to unfortunatly. And as you say, if I could do that, I'd draw the picture myself. The sketch you did would work just fine, maybe if you just sorted the aspect I've already mentioned. Though I do really like the position of the Dragon on the left, and it'd be a shame to lose that. Perhaps if you made him crouch a little lower, he could enter the other Dragon while he was standing on the ground. Or, another idea would be to leave the Dragon on the left as he is, and perhaps make the other Dragon slightly bigger, so his increased height would allow him to stand on the ground. One thing I'd like to suggest is some great expression on the two Dragons' faces. They are both getting a lot of pleasure from the expreience, and I think that should be shown in their expressions. I also think it would be more romantic if they had their heads next to each other, perhaps the Dragon entering, on the left, could have his tongue caressing the Dragon being entered, on the right. I hope I made this clear to understand.
