Nat - Thanks for taking care of the cookie image. Since we are a startup company, we do not have our product photography yet. But, we expect our cookies to look like these
http://www.stonybrookcookie.com/cookies.htmI am not an expert on the topic of artistic design. I do like the cartoon-like image (lack of a better word) of the cookies that you created. It is FUN and just feels right. I think if we move too close to photography (for instance) this logo would take on a too polished look. And that's not what I am looking for.
Dealing with children's cancer is serious and all too often sad. But if our logo is fun, playful and happy, it speaks to people.
You may add more realistic details to the cookies, but don't go too far.
Sorry to be so opinionated on this. I truly appreciate your patience and dedication to this project!
