As you can tell, I like my photo. But a lot of that has to do with internet branding, it is all over the internet. I think that the best photos are always ones with you and your product, something fun. So, I can totally see yours being a hot picture of you, close up, wearing some eye shadow. Like just focusing on your eyes. Similar to the one I posted below. I am thinking more glamourous. Spend a lot of time and energy on it, get a student photographer (they typically will work for free). Then use it as your tradmark photo, include it in all your marketing online. So, like your avatar everywhere, and maybe even your shop banner. I'm getting excited actually... It will make you seem more professional as well.
