Many thanks for the replies gents

Are those led strips?
Yup, and plenty of them. I'll be putting a frosted sheet of acrylic between them and the ceiling to tone it down a bit as there's only about a third done at the moment.
but how playable is that? You've got the figs hemmed in on all sides if you have your ceiling in place. How will this sit on your board? I'm struggling to understand how this all sets out! I ask because I'm looking to steal ideas get inspiration.

The ceiling is removable and I'm tempted to have it next to the actual board. It's still in the 'design' phase at the moment

Have to be honest though, am not keen on the thick bases for the minis - sorry

All the bases are 2mm thick but a few have an extra pavement layer which is what you can see the back of.
cheers
