I hate being the one to do this, makes me look like I'm being too picky.
The only actual problem I have with this is the word Tarawa, which would make some of the details of the diorama inaccurate. Maybe just use a different word like Peleliu maybe, or Okinawa which was hardly defended at all and this would be more feasible. At Tarawa the majority of Marines walked in, which means the water depth was about 2 to 5 feet on the reef, which covered about 500+ yards from the beach. It was also shot at pretty heavy and wouldn’t be this nice looking, the beach that is. There was some area that didn't have a wall, barrier or Japanese emplacement but not much.
Now having said that, very nicely done on the LCVP, like Scott I really like the water discharge, I haven't ever been able to do it as realistic as this. Nice weathering on the outside and also from the little amount of the inside I can see. Would like to see more photos and please add a word or two on the water.
The last photo was very hard to see any detail due to the lighting.
Overall very nicely done, congrats,
Bob
