Made this for my friend's birthday (2 days before exams, yay!) In the last minute, I made minor changes and didn't scan, so this is a mobile photo from his phone. I have a scanned version as well (which I put in the spoiler tag if you want to look). Done rather quickly and I know it has shortcomings but I was on a tight schedule :/
Spoiler: show
Scanned (and with the errors ):
