I don't think so... rather cluttered design and doesn't mean photography for me.
This isn't for a charity, it's a business. I don't know if the OP is with the company (SunFrog) or is getting opinions for licensing a T shirt design thru them.
Either way, these things always get me curious, so I end up scrolling to the bottom of the website and nosing around...
Red flags were not being able to find out where this was located, if it was a legit business, ownership info., etc. (I did find the info. on the Press page but took some looking; appears to be a legit business operating as an LLC with physical office/production space.) And not being able to find pricing/percentage of sales info. for artists/affiliates; It might be on there, I took a quick look at Terms etc., but didn't see anything.
So I wouldn't use the site based on what I read under Artist and Affiliate sign up or Terms & Conditions, etc. If designers aren't compensated at what seems like a fair working rate I wouldn't buy from the company, and I can't determine that from the information I found.
