Watercolour on paper
Now I remember how annoying it gets when a flying insect lands on your paper while you're doing watercolour(It's been a long long while and so I'm trying to shake off the rust). For that split second you go, "don't you, don't you frickin dare." And then you blow it away, hopefully in the right direction. Tonight I've been rather lucky.
(Shitty scanner, if I get the chance I'll try and get a better scan/photo.)
