I am finding this build rather odd. I guess Italeri must produce this kit for Tamiya? I am finding the plastic very soft, like cutting butter with a steak knife, and the detail is....OK, not great. Meanwhile the resin upgrade kit needs a lot of trimming and fitting, but I was expecting that anyway. The next step will be to fit the resin upper hull to the plastic lower hull. It's hard to tell from the pictures but there is a prominent bend in the bottom of the resin hull and it will need to be massaged into place with hot water and patience.
