Yay, I won something!
As the dust settled after the last round of the Iron Painter, it turns out I won the prize for the highest score!
Technically, the highest score belonged to Curtis Shoemake, who won the whole contest. But the rules stipulated that one person can only won one prize. So since he got the $500 grand prize, he was not eligible for the highest score award. And apparently my entry from Round 1 was the second highest with a 54.
I got a $50 check and $50 store credit. Thank you Wyrd!
