Seems better.
As for FM/43, on the current version, the side "wall" of the main casemate looks like it was slightly rounded along the top and rear edge, which IMHO wasn't the case. Generally it was that kind of things regarding shading that, especially in the first series You were doing too much. If some surface is flat, then it would be in only one shade (except something above it casts a shade, of course).
