Looks good although there is no reason what so ever to run 2 fuses on the same line like you have pictured here drop the second set on the 1 pair of wires save yourself the money.

If you only fused at the front battery, the rear battery would start the fire if the wire between the front and rear battery gets shorted out somehow. The rule is not 1 fuse per wire, the rule is 1 fuse at every source of power - so if you have 2 batteries connected via the 1 wire, you need 2 fuses assuming those 2 batteries are very far apart and you are running the wire through the chassis of your car to connect them - one at each battery.

Exactly.
