No.

The default gateways for both PC's are incorrect. For PC1, it should be 10.3.3.3 and for PC2, it should be 10.4.4.4

Also, not everyone has Visio. I suggest you use JPG or PDF in the future.

That is correct.

In your scenario, each PC is on a different network (VLAN).  This means that each switch will need a VLAN 3 and a VLAN 4 interface (with IP address, of course). Then each switch will need two VRRP instances with a defined VRRP IP address.

Switch 1:
VLAN 3 IP: 10.3.3.3
VLAN 4 IP: 10.4.4.2

Switch 2:
VLAN 3 IP: 10.3.3.5
VLAN 4 IP: 10.4.4.4

VRRP address for VLAN 3: 10.3.3.1 (this will be the DG for PC 1)
VRRP address for VLAN 4: 10.4.4.1 (this will be the DG for PC 2)
 
Also make certain that spanning tree is on!
