I like it and love clean panels BUT
(a)Get rid of the silly bottle holder
(b)You don't need a separate AoA indicator; that'll be on the EFIS
(c)Why (nowadays) have a separate avionics switch? If you don't trust the resilience of modern electronics to handle the start up voltage 'spikes' (which they do) then put something like a TCW IPS behind the panel.
(d)Nav/Strobes and Landing/Wig Wags could be combined into 2 x 3 position switches
I wish I didn't have to have backup ASI, altimeter and compass or else your design would almost be my Nirvana
