H-Bridge using relays and Transistors

hello all,
i new micro-controllers , trying create circuit linear actuator actuated timer.  the timer being user interface mod ic program actuate @ exact hour of day extend actuator , retract time period later.  i have read multiple threads  but none incorporate h-bridge relays transistors.  i open , , advice how can make circuit better or more efficient.  i still learning how code look, advice circuit.   the schematic attached below.

specs:
linear actuator draws 1.5a max , full cycle 40 seconds internal cutouts @ full extend/retract
arduino uno
sainsmart 4 relay module, relays draw 15-20ma driver
transistors 2n3904

the system powered 12v battery maintained 5w solar panel/controller.

thanks in advance input or suggestions.

here approach (attached.)
it doesn't show relay coils, contacts/switches.
