Crop from the hi-res
Herschel is a complex crater, and what we see inside it is the central peak.
The shape and the distribution of the central peaks are subject to several different variables,
like impact angle, strenght of the impact, composition of the soil etcetera.
For this reason you won't never find two identical composite craters.
An example is Bessel
Another one is Euler
Another one is Copernicus
Another one is Tycho
There are MANY examples
The central peak is an ordinary feature in the larger craters,
and the central peak of the one of the OP doesn't look less ordinary than the other ones i've seen so far in lunar craters.
