Figure I'd post mine, might not be great, but whatever. I put in Ubercart on Thursday I think, so don't mind the design crappiness, i'm still getting used to it 
Site looks like a great start! I like the custom theme job and would maybe recommend removing some of the "busy"-ness of the checkout page... like trimming down blocks and things for customers to click on instead of giving you money. 
like having just one column of blocks? this theme doesn't make the sidebar smaller when i use either right or left blocks so i gatta figure out how to do that ... and i suck at css, so you can imagine the fun i'm about to have hehe
Actually, in the block settings, you can specify what pages blocks should appear on or not appear on... I do that with a simple wildcard. For example, on the Livetest, I have the cart block set not to show on pages cart*... so any cart or checkout page doesn't display the shopping cart block.
I apologize for being slow, but after about 15 clicks I couldn't figure out what you're selling and how to get to the cart. Can you tell me?
The word "written by ..." on top of each node threw me off. I was trying to find text not realizing you've been posting images without text.
I like the design a lot.
What theme is this?
Are you pulling the images from Flickr or are they on your own server?
