# Constructive feedback:
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.

# No problem
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?

# 100% Correctedness

# no i'm just playing
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.

# That's perfectly okay for HDR
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.

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

# It seems like that should work
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.

# ur doin it wrong etc.
You need to take multiple shots with different exposures - you have a D70 so you can do that fine. You'd want a picture with a high enough exposure to get the details on the buildings for it to be a good looking photo though.

# Ooo that's lovely ...
I love cityscapes at the mo. This is in Illustrator, though:
