I thought I would share this since I have already successfully attached it to a few commissions. These are my terms, as a customer purchasing a commission, which allow me the full enjoyment of the artwork I commissioned. I have been inspired to do this based on some bad experiences my friends and artists_beware have brought to my attention, as well as some bad experiences I had commissioning artists as well.

The artists I commissioned who I showed this document did not have a lot of clear terms of sale of their own, but they were agreeable to it. I'm not sure how well it would go with an artist who already has a ToS with some contradictory terms in it but I shy away from those artists anyway, I don't usually find artists with restrictive rules for commissioners provide a better product that's worth it.

You can check it out here http://quakefox.com/rider/ and I'd be curious what people think, in particular artists who accept commissions. By the way, I have never presented this as a take-it-or-leave-it and would be open to negotiating anything.
