The biggest problem is that it's crude. Check the photos in this review:

The mantlet doesn't sit level. There's a joint all the way around the upper turret wall, this guy must have worked hard to make it invisible but he failed -see the last photo. The glacis plate doesn't sit right, according to this guy:

Concerning general accuracy, , I can see these issues:
The cupola slits are too wide and are rotated from their true position; one of them should be front center. The real cupola didn't rotate.
The front edges of the turret walls - visible in the gap behind the mantlet - aren't a scale 80mm thick.
There are strange little rings on the front towing hooks, they didn't really exist.
The turret has 4 spare track holders on each side. In face there were 5 on the left and 2 on the right.
The turret bin is the standard type, tapering outwards. This type never had support beams on the side.
Concerning accuracy to represent Tigers of a specific period, I can see these issues:
The exhaust shields are of the Africa type used only by s.Pz.Abt. 501. Most of the kit agrees with this, but:
The tracks have cleats on their surface. These didn't appear until October 1943 so they are wrong for this kit.
The Tigers of this unit had a wider turret bin with parallel sides, so the bin is wrong. But it did have side supports.
The handle on the glacis was a field modification only seen on the Tiger in Bovington Museum, so it's not needed.
There are 3 rods stored on the roof each side of the turret; but in these Tigers the rods were longer and there were only 2 on the left side.
These African Tigers didn't have spare track holders on the turret at all.
The cable stored on the left side of the hull is arranged according to a pattern not seen until much later. These Tigers had more clips in a very different layout.
The rear mudguards are of a later type, only the front ones are correct for these Tigers.
