Chess Pieces

Better late than never, here are my simple designs for a few chess pieces.

The theme of my chess set is 18th century piracy, with pirates versus the British Army.
The rooks for each side are canons, which would have the ability to attack in straight lines in any direction from the square they're on.
The bishops are a Royal Grenadier and a pirate equivalent, both with the ability to throw bombs which would do damage in a certain square radius.
The pawns are basic British linesmen and pirate peasants, which would operate roughly the same as pawns in a regular chess game.
