Hi Jack,
I like your logo and JHouse branding, I think the colours work well together and overall it's got a nice visual look. I would personally look to have larger images of the work, and more of them on the page, perhaps separated by category, so by 'BRANDING | PRINT | WEB' as you have in your signature. I think that many visitors won't take the time to scroll through the thumbnails to some of the later work and will lose interest before seeing the work you've done. There's some really nice work examples, and some great bits of print design, so if the work was easier to access and view I think visitors will get a better idea of what you can produce.
Some form of introduction on the site would be beneficial too, as for someone landing on your site, with no prior knowledge of you or your work, it may take them a while to figure out what you do and what you offer clients. Other than that I would make the About page an actual page, perhaps extending on the services you can offer.
Thanks,
Greg
