I worked with a CSS designer, and we came up with this first revision attempt.

Ah very nice! Graphically pleasing and looks like a quality check.

Will the graphics be available for use on bitaddress.org ?

Bitaddress is user pointbiz, who just posted before you, so I imagine you're in luck in terms of contacting him.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper wallets instead.

Would it make sense to add a QR code with a bitcoin address for receiving change?

Currently using the bill to replace cash means that you either need to have the exact amount or else cash would be needed as well to supplement the payment amount or cash would need to be given as change.  With an exchange that floates, prices are probably not known until payment is made so the chances the buyer already has a paper bitcoin in the exact amount would be even more less-likely to occur.

If instead the paper bitcoin also had an address for receiving change, then the buyer could just carry a paper bitcoin(s) totaling at least the purchase price.

I see there is enough room in one of the unused corners for another QR code where the bitcoin address for the change could go.

The receiving address could even be a specially marked paper bitcoin, meant primarily for receiving change but could also be used for spending

Ughh ... this just makes the paper bitcoin even more complicated and not less so.

Nothing says the change can't go back to the same address.  Worst case is the machine that gave the change could steal it sometime later.  That risk could be offset by using only small bills.  The machine could offer the option of sending the change to a new address, or just leaving it behind on the same address.

I am looking at it more like a personal check. Once received, you hold it if you trust the person, or you deposit (redeem) it into your personal account.
Then throw the paper away.

For anyone immediately writing this off because it'd make their wallet look like their wife's purse (with a bunch of coupons and whatnot in the same compartment, which drives me nuts) - they do sell multi-currency wallets. They're generally listed as "double billfold wallets" for travelers and those in a country with multiple well-accepted currencies (more often, somewhere with a horrible national currency and then a slightly-less-horrible currency like USD). They're often outrageously expensive due to stupid, but you can find some decently-priced ones on Amazon.

Don't mix your coins someone said isn't legal
