An ATC with an Unusual Surface

Yep.  Another interesting challenge.  I  looked all over the house and one afternoon I was staring blankly into the corner whilst sitting at my desk and I noticed a USPS Express envelope sitting there.  "Hmmmm..." I said to myself.  I cut an ATC-sized chunk out of it and got to work with alcohol inks.

What do you think? Kinda different, yes?
