My thanks to Vraciu for his feedback, patience and tips and of course to Lyric for his help (as usual) in finding information on this aircraft.
Less than a year after its baptism of fire at Port Morseby, 75 Squadron returned to New Guinea and soon after newly promoted Squadron Leader Geoffrey Atherton assumed command.
By this time the surviving E models had been phased out, replaced by the newly arriving models. The aircraft chosen by Atherton was one of the first N models that the RAAF received arriving in August of 1943 and was painted in US version of the colours stipulated by the RAAF, the dupont paints weren't an exact match though.
No. 75 Squadron moved to Goodenough Island in October 1943 to support the Allied offensive in the Louisiade Archipelago and New Britain
Again named Cleopatra this remained his aircraft until he moved on to his next assignment.

That looks really good.
Here are some areas where I think some adjustment can be made to make it even better.
1. The demarcation line for the underside color on the cowl seems too high, especially towards the front. Typically the colors change near the panel line lower on the cowling. Maybe this is something seen in Lyric's reference?
2. The demarcation of the wing camouflage colors seems to be the seam between the upper and lower wing halves on the bitmap. I would add the top colors to the leading edge of the lower wing half and blend it in to the demarcation line on the cowl. I can only see this issue inboard of the landing gear housing because you have the white ID marking outboard, but I assume it is the case for the entire length of the wing.
3. The underside color is too light. It seems like it will glow pretty easily if it catches sunlight when banking or inverted.
Overall you're making some nice improvements with your skins.

Edit: Here is the cowl area from my in-progress P-40N template to illustrate where I have the demarcation line.
