You mean you're the one who got the Audubon gig when I refused to go cheap? Good for you!
Or, that you're simply starting out inexpensively to get the much needed recognition? Nah, do it however you wish to do it. It's not for ME to approve. I'm just one person. Do what feels right to yourself, but don't de-value YOUR work or YOUR worth!!
My lesson in underselling myself (and basically others) came from a major cartoonist here in town. I allowed free use of Muley Comix comic strips in a local publication, and then when others were trying to sell strips, they said they had a free one, why pay?
When I realized after he explained that I wasn't just underselling myself, but decreasing the value of my craft, as well as the hard work of others, I withdrew my strip, and then offered it to them for sale. They declined. Now, there's a high-school kid doing those strips for free. Exposure ain't what it's cracked up to be, gang, so when you hear that, DON'T let it fool you. You can't feed yourself on exposure (unless your a stripper at a club).
Anyhow, sure, start out light and easy just to get yourself known, but start kicking your prices to where they should be as time passes by.
I am curious to see the work of the builder that the Audubon guy hired. I took actual puppets with me to the meeting to show him my work.
