You have achieved some great results here, Sometimes you can get as good of a result with the Pseudo HDR as you can with an actual HDR composite, which is 3 or more images at least 1 stop apart shot using a tripod. But the actual HDR image gives greater detail and the dynamic range between the highlights and shadows is fantastic.
Pseudo HDR
Actual HDR
Although not the same image you can see how the colors pop more and some of the differences in the two.
Hope this helps some, Your shot looks great as it is though.
