As for the hood I would suggest either no hood or one shaped like an MGA where it is rounded in front, radiused slightly over the top and curved forward across the rear.
A two piece butterfly hood set up might be simpler though with a center support going from the cowl forward to the radiator shell support frame. You could use a piano hinge on the tops and slick leather buckles on the side to tie back into the 20-30's style.
Hell you are doing great on your own. Don't listen to anything I say.
Looking forward to more.
