Looks like a great start, congrats!
Some things to consider, nothing new here:
Adequate lighting at the correct kelvin temp
Adequate power (more is always better)
Proper flooring - chemical resistant
Access to a good video monitor for how too's
Exhaust removal system
Clean and dirty work benches
Adequate wall blocking to hang heavy items - like tire racks etc.
All interior finishes should be easy to clean
Don't skimp on insulation, spay on is preferred
Ceiling fans/cross ventilation
Proper structure to support a hoist
Be sure it's kid friendly, lockable cabinets for chemicals etc....
Some durable but comfy chairs
......the list can be endless, good luck!
The faster you go, the better it feels
