Terry, if you want to learn more about spectra and how to analyse them, I can give you an exercise I used as part of my course, dealing with spectra and how to interpret them. It's quite interesting to do the exercise
However I can tell you that the broad peak you've got near the beginning is most likely a NII/III line, down around the 450nm (4350-4550A) area. If you look at the CDS graph, you'll see the peak right at the beginning, that would be your HeI or even II peak. The Ha line would be emission from hydrogen present on or near the star. WR stars are typically hydrogen poor in their spectra (usually none) and where a strong Ha line appears, it's most likely from one of the least evolved of the type, a WNL (late type). The strong NII/III (ionised Nitrogen) peak indicates it's a WNL star and probably a WN7-8 by the strength of the peak. The strong CIII peak is unusual in that nitrogen normally predominates over carbon in these types, however there is some carbon present in their spectra.
All in all, that's a nice spectrum you took there and a fine job taking it
