I'm not sure how to advise you, as I havent worked with HDR. HDR seems very difficult to apply in effective and subtle ways. Your image does not appear quite realistic and I'm not sure why. Probably too light in the interior.
It seems soft and it looks kind of washed out in the colors. The reflections of the cushions on right are really wierd (ghosting).
You have some text showing up on table leg under glass.
I think you have chosen a subject that does not work well with hdr (reflections, moving leaves)
Tell us about your technique. Tripod, how many exposures, which software.
Best technique is use tripod with multishot on and either timer or remote shutter. If there is any movement it will show up as soft because HDR cannot resolve where pictures difer. Obviously if there is any wind in trees the leaves will look soft.
Using highlights and lower saturaton would improve.
Thank you guys I appreciate the input It was a 3 exposure shot off a tripod with 2 second self timer the text is actually the photomatix software watermark that is there while using there software during the trial period.

I also think that the interior seems too bright for the scene to be realistic, even though on second look the extra reflections indicate that the room is probably lit through windows on two or more sides. In that case I can't see why you'd use HDR to brighten it up.
It is also a very busy scene. Perhaps using a polariser to partial effect would help but probably not - you'd be replacing busy reflections with busy seen-through-the-table details.
A bit of sharpening would help too. At least then the business would look like it's well focused
By the way when I use photomatix, just hdr, I have found that universally it makes the exposure overexposed so the first step is usually to turn down the exposure before adjusting the tiff.
