Working with VRay HDRI

Well as the title sais I been working all day with VRay HDRI and the result, well lets say I either need a better HDRI image or I'm having some trouble setting the option on it because the best result I got was this.

Now it might be because I not using VRay materials or maybe im letting too much light with camera but I can't seem to be able to get something better. I will be trying some VRay materials I found from the internet today so hopefully this gives me a little better results. Well after some quick touch ups in Photoshop and I got something with a little more contrast.

Hopefully with a little bit more testing I can get better results.
