Hi Brian,
Welcome to CiC - great to have you with us
I had a quick read of your tutorial - three things came to mind ...
First up, it's nice to see people making the distinction between psudo-HDR and HDR (or HDRI) - you wouldn't believe how hard I sometimes have to work to get that through to people!
You mention that bracketing is 3 shots, but it can be any number. Most cameras will do 3 by default - mine can do 2, 3, 5, or 7 - but one can also do as many as needed manually.
The last thing that came to mind though was with the photo that you used - to be honest, I think it would have looked better with just regular post-processing.
The big "problem" with psudo HDR is that the images don't contain any info over and above what's in a single RAW shot. Traditionally the process
can make it easier to get at the info, but with powerful controls like "fill light" and highlight recovery now available in Adobe Camera RAW, I really don't see any advantages in the psudo RAW approach anymore ... in most cases it just seems like many additional steps to achieve the same (or worse) result.
