This is a particularly poor subject for HDRI since there's such a low dynamic range in this environment to begin with.
HDRI is most effective (and was developed for) environments where there's a particularly wide dynamic range which is impossible to capture in a single shot.

i think thats the first time i've ever got constructive feedback on here, mostly its abuse, surrealness and CDCs

but reading your comment here I don't think I've understood what it is you're doing.
My understanding of HDRI is that it's constructed of multiple shots of the same scene taken with different exposures and then combined. From your comment above, I don't think that's what you're doing here?

i figured i could get the same effect by using one pic then altering the exposure in the raw file processor to get three separate images with different exposures, then combining the images. will this not have the same effect as three separate images taken in camera?
i was being lazy, that might be the problem.

It's just not as good as several images. Especially if your camera doesn't have a particularly broad sensitivity.
The purists go for several images over quite a wide range of exposures.

i'll do it properly next time and post results here for all to see

but it won't produce the same results, because whatever exposure you choose in the raw settings for a single shot cannot reveal details which were not within the exposure range of that shot. The idea of multiple-exposure shots is that you can comfortably extend the range beyond the exposure capabilities of a single shot. It really does work and is well worth the trouble. Choice of subject is really important though. Choose something with a very wide dynamic range to begin with.
There are lots of tutorials online, some of which are excellent.
