Singapore Cider

I keep VERY IRRITATINGLY forgetting to take my sketchbook out with me. I think with the weight of two cameras in my bag I assume it's already in there. But I managed to remember the other day so while I was enjoying a glass of "festival strength" cider I worked on this little drawing of Royal Tenenbaum and Chaz Tenenbaum's kids. Can't decide whether to watercolour it or digitally colour it. What do you think?
