Super-subjective and from the looks of the other posts – and the screenshots – a minority opinion.
I have FR, AH, and FI Spits. They all look great, IMHO. Sorry whatever quality you’re looking for in the textures isn’t there, but these are professional and highly accurate. I get that some people look for specific characteristics – exaggerated aging and weathering, specific shines to paint, etc – but again, subjective.
Comparing all three, I think anyone finding fault with the texturing/detail on any of them needs to be sent back in time to play Combat Flight Simulator V1. Or maybe Aces Over Europe.
