Can we get a more elaborate definition for what you consider HDR? Neither of the two submissions so far are actually HDR in my opinion.

As per Wikipedia:
"The two primary types of HDR images are computer renderings and images resulting from merging multiple low-dynamic-range (LDR)[5] or standard-dynamic-range (SDR)[6] photographs."

IE, merging together multiple exposures of the same scene. The two submissions already posted are only single frames.
