That looks like a fun kit and great for beginners. The glasses insert is brilliant. I don't know why the goggle makers don't realize a large portion of their audience needs corrective lenses and put a diopter adjustment on them like binocular, scope, and other lens makers. DJI makes some +2, +3 etc. inserts for theirs that drop in and out, they actually work pretty well, kind of like yours. I'll be interested to see what you do for battery increase, that 3 minutes doesn't seem like near enough time to get your bearings, let alone get in an actual flight. I would think want to at least triple that time. Still looks like fun to try some of those acrobatics without breaking the bank.
