I would have taken a different route on the frame but I cannot fault the concept.
The chrome plating appears outstanding, I would have been fearful to take so many small parts in.
The cleaning up of the rims is just right.
I have never seen Zeus cutters before.
As others have mentioned I would level out the saddle and consider moving up the brake levers on the handlebars, reference some old pro racing images for a guide. To keep it period, I would go with cloth tape in white or red. Source some toe clips and straps to finish off the mechanics.
