That looks relatively normal.
However, how many exposures did it take to reach that result? By the time all those captures are made the light would have changed (think golden hour) and clouds would have moved, too! It's a bit impractical, would you agree?
I am aware of Dr. Paul Debevec's pioneering work in HDRI and global illumination (I was a 3D modeler/animator). Fiat Lux is what got me interested in HDR.
