Looks like a major "bitsa", I mean the Entwicklung series of tanks were supposed to be "bitsas" (bitsa this, bitsa that) in an attempt to standardise parts production, make them modular so maximum amount of parts was interchangeable between different types of tanks.

Looking at it, its like a Panther with a Sheridan or Russian inspired (although not) turret, KT tracks... honestly I think its ugly as sin lol
