That isn't near as hazy, but it's a little over-saturated and you are losing detail. Keep it simple and you'll find yourself getting a much better response. Take it from someone that wasted time with HDR a few years ago, editing isn't where you make it. Focus on composition and exposure, the fancy stuff will come later.
*saw the other shots* Composition wise, you are getting some good stuff. Most of it looks underexposed though. Also, the editing on the shots is inconsistent, find a white balance or color profile that you like, and stick with it for the entire feature/coverage. Personally, I like the filters on the Ferrari and Evo shots the best.
