Good-looking P-40, FTJR.  I want one!
The hues of the green and drab look quite believable to me.  Some engine soot/exhaust stains aft of the exhaust manifolds might look well on her too.  From the extent of the leading edge chipping/wear of the wings, she looks to have seen some use.  And maybe trailing the underwing shell casing ejection ports.
Really nice looking bird though, love the underside shot.
