nice work Jadehawk

I think the Reggiane Re2005 is the best and beutiful italian aircraft,
about your color profile I think you have to work on the shadows and light for make more 3D effect,

the wing the undercarriage look very flat, you have to check the carburetor's air intake look a little bit strange...
I suggest you to look all the photos you found about this subject can help you so much

cheers
