portfolio/gallery

I want to create a interior design website. Under the portfolio i have residential, commercial, so on... inside each category I need to create another portfolio, for example: portfolio-> residential design -> X project -> Y project, so on here is my portfolio http://69.195.124.63/~kzinteri/portfolio/ here is my residential design folder http://69.195.124.63/~kzinteri/portfolio/residential-design/ I really don't like how it looks. I want a clear look as in the portfolio page. I tried to add a gallery and add a link to each individual image, but didn't work. also i tried to add a extra portfolio plugin but it also didn't work. what would you suggest? thank you
