Personally I'd close the gap between your contact details and the name on the home page to make it look a bit more 'placed' (I feel like that makes sense). Also the text under Automotive says that your details are at the top of the page when they're not, not sure if you intended the email and phone to be in the same position as the home page?
And like JD said, personally I'm not a fan of slideshows (or really anything that changes unless I click it) and think the sizing as now with scroll through thumbnails along the bottom would smarten it a little with the benefits of picking and choosing more.
There's my unprofessional opinions It is nice as it is though, that's me looking for improvements.
