Nice j0b on that conversion! That has always been one of my favorite "oddball" aircraft mockups/spoofs.
One major problem with the conversion, however - you used the P-40E Allison engine cowls. If you look closely you will notice there are NO intakes on the top of the cowls in the photo. This makes them the Rolls Royce engines/cowls used on the P-40F/L.
