Bronsted vs Lewis

What are the main differences between Bronsted and Lewis acids and bases?

Bronsted looks at protons, while Lewis looks at electron pairs.

A Bronsted acid is something that is a proton donor, while a Bronsted base is a proton acceptor.
A Lewis acid is an electron acceptor, while a lewis base is an electron donor.

If an acid is an electron acceptor, whilst giving away the H+ (which is essentially a proton), how does it take in another electron? or does the electron already exist to the acid?

I think the electrons that the acid is going to accept will come from the base that is donating the electron.
