you config is prefect except you missing 
ip nat inside static source list ....interface overload 

[balaji.bandi · Accepted solution]

try below config - make sure you understand the config before you apply :

interface GigabitEthernet0/0
shutdown
no ip address 172.16.4.145 255.255.255.252
no ip address
no ip nat inside
no shutdown
!

I am not sure of the logic for BB in moving  172.16.4.145 255.255.255.252 from the physical interface to a subinterface. But I agree that he does address several serious issues in the original config:

- none of the subinterfaces included ip nat inside (probably the most significant issue).

- the configured static default routes (there is not anything else in the config about 10.10.10)

- changing the acl for NAT from an extended acl to a standard acl. I have seen issues when nat was configured with an extended acl which permitted "any".

I am not sure of the logic for BB in moving  172.16.4.145 255.255.255.252

I move this to make it neat since OP uses sub-interfaces for other subnets.
