Weird Science

Was asked to make science themed card for a 16 year old. Accepted order without a second thought and the panic set in! What on earth was I going to do for it? 
A trawl through the internet turned up the mad scientist robot image which was perfect! 

I then pondered what to use for backing paper and spent about 3 hours looking for something perfect. Finally found the blackboard image with scientific formulas so used that with a yellow and red checked paper.

Typed and printed the sentiment (which I had to replace twice due to spelling mistakes). Image is before I noticed the second mistake!
