The best thing about your drawing is the setup and the incredible humor that comes with it. It really brings out the funny side of each of the characters. This seems so natural that I'm surprised that something like this didn't happen on the show itself. XD Your style also really bring that out enhances the setup's humor and makes the Doctor and River feel alive. The rubber duckie is a perfect accent for this, drawing your attention to it. Plus, it makes whole context of the humor worth wild. The comments add the subtlety needed to pull the humor off. The only suggestions I have are for minor details of the technique. I suggest that the darker shadows in the drawing to be darken a bit more, so that way there's a little more depth in the drawing. And, that's about it. This is a wonderful piece, great humor, and overall an Awesomeness!
i love it i cant believe i only made an account a little wayl ago but i mite sound a bit weird but i love this pic because the DUCK ARE COOL and I think that River and The Doctor mite have a bubble bath but it could be better if Jack came out the bath and start to flirting with River i not shor wate River woad she could said to The Doctor let's go out and then she will get wot she wonted but if she flirt withe Jack The Doctor mite get jealous and stand closer to River and she will get wot she wonted so she will have The Doctor.I love it you are so tainted.
