Empire Line

Trying some ideas out for a project my uncle is starting up. Lot's of work still needed.
I would really appreciate any advice from all the awesome type pro's out there. Not sure what to do with the P and R in first two versions and what the dot above the i (tittle is it?) should be like.

Also any tips that could help get cleaner results when converting to vector would be appreciated too.

Any comments, advice, general banter all welcome.

Cheers
