Day 41:

"Think big.  Create a large version of something that would normally be much smaller."

I decided on a Bull Ant today.  I lived in Australia for six years and although Bull Ants are big (they range in size from 8mm to 4cm) they aren't as big as I drew at 23cm.  They can give you a painful stings by gripping you with their mandibles, curling their abdomen and injecting you with the venom.  I have seen them but happily was never stung by one.
