I’m sorry but the Graphics and colors Seem terrible to me. Almost unbearable.
I think you need to come up with a new, unique concept, and then design around that. Vintage can be done so much better. Maybe Browse some css galleries, find some inspiration, and then think up a unique Interface.
I like your sans-serif headers, but you need to focus more on spacing and whitespace.
You only have a few graphics made up, so personally, I think you should really look at the re-design before you invest too much time into this theme. The niche is hit or miss, and sorry, but this just misses completely for me. I would not spend much time on this site, had I landed here.
Just trying to be honest. Please don’t take my criticism the wrong way. Of course, in the end it is your site (personal blog I assume), so do what makes you happy.
