I reckon you could just go with octopus if you want... Nothing wrong with cheese... and even then it's not really cheesy? just because you didnt think about something much doesn't make it any less awesome. In fact, thought is quite overrated. All the worlds greatest thinkers recommend against it. And beside, he may even be honoured or something along those lines by the fact that you have turned his photo into a drawing?
But maybe you secretly just don't want to draw an octopus and you are using the whole cheese thing as a cover for your octopus hating ways?!?!?! That's it! You're an octopus hater aren't you!
But putting your specist views aside
You could do some moshing metalrs going hard to some harp whilst scientists gather up the sweat to clone them to make a hoarde of metalheads? im not sure why they would want to do that? but you know what those crazy scientists are like!
Or you could make it less silly and more personal. And so you bonded over joanna newsom? how about you draw something relating to that connection? Or you could draw a picture of the two of you listening to it, Or you could draw a picture of the two of you watching a capsicum listening to joanna newsom... everybody loves capsicum. and you could both have lab coats on and watching the capsicum would be some crazy experiment in the name of SCIENCE!!! and somehow contributes to curing cancer.... or something useful like making chain capsicums grow
Or you could just give him a postcard of scribble and say it's a conceptual postcard about childhood and fish
Or you could peel potatos until a good idea came?
And now I'm going to run away....
