Driveway with retaining wall, suggested plans

Hi,

I'm new to construction, so I've sought advice from a few people and resources online.

I'd really appreciate someone to have a quick look to see if my plans are ok, or need adjusting.

Sorry if a lot of this stuff is basic, but I didn't want to assume anything.

As well as checking over plans, I'm not sure of:
1. Do I need to first lay any aggregate above (very hard, dry) clay?

2. Is the depths of footings enough (see plan)

3. Do I need to think about internal drainage, or will I not need that if I’m using concrete or monoblock paving?

Thanks a lot.
