True is that this offering is further with many small details than all previous Sherman offerings, but you don’t see many of these when finished.
The surface of the rolled armour plates is quite strange, whilst only MENG and Dragon on some kits tried to depict something like that before, I am still more than happy with Tasca/Asuka and Tamiya plain surfaces. So no improvement her in my opinion, actually the contrary.
The engine compartment bulkhead is missing, while the kit construction and warping of many parts would make it quite useful as it is much more difficult to be built properly aligned than any other from the similarly constructed competition.
As you wrote, the kit is late WW2 version, but with the T80 track, which was quite rare then. This configuration is wrong for the Paper Doll marking. For post WW2 appearance you need some more appropriate bits, for the WW2 one the possibility to choose between the T66 and the T80 tracks would be nice. In this regard - Tasca/Asuka T66’s do not fit the RFM sprockets without some surgery, their teeth are too thick.
