Foundation size depends on the soil type.
Sand or gravel require largest foundation

Looks fantastic. The boulders add a nice touch.

Through this thread one thing is missing. OP states the ground rod is also buried with a wire coming up out of the concrete. Inaccessible ground connections are required to be a welded connection. Electricians use a thermite welding process to bond dissimilar metals (the ground rod is copper clad steel not solid copper). DIy process is to Bronze weld it with a torch. Bolted connections will corrode and lose their conductivity fast in normal soils and faster in acidic soils. You definitely want to bond the pole to the ground especially if it is powered. There may be an interface device to install between the pole ground and the electrical service ground to prevent a lightning strike jumping into your house panel. Also bond to any outside source of power (there are several code issues here that vary by jurisdiction regarding grounding and bonding. If you are not using an electrician recommend you get a copy of "Soares Book on Grounding and Bonding". It is based on the NEC only. Worth its weight in gold to eliminate the bad dope surrounding this issue, even electricians refer to it all the time.

I am surprised our electricians on TBN have not caught this.
