'Til the cows come home

I know, it's a photo of a computer screen but in my defence I'd submit to the court that I haven't done anything else today. As soon I got to switch off my work email and put that behind me I sat down determined to finish this. It started on Tuesday at school - draw 'til the cows come home - and I came up with various stupid cartoons, which I think was what made me determined to do something slightly better. Anyway, it's taken me all afternoon. And now I need to do my homework for next week.
