The theme is not bad but it does not look good with the content of your site. It's difficult to read the white text with the yellow background. I think you should get a logo and change the theme of the site.
I have to agree with King. It's not a bad theme, but it's hard to fit in with the content on your site. Definitely get a logo or make one for yourself and change the theme so the viewer can easily see your works, but at the same time unique to their eyes.
a logo will go well with this site, also try something with the text by placing a light white background behind the text as the text is hard to read with the background. but i like it!!!
