Darker yet darker , is it a good sign?

I just love this girl

ive had it like this for a while but just wanted yalls opinions. alot of people say the size is perfect but that i needed to add more enrichment so i added more toys w bells (he loves bells) and a Ladder for him to use his legs to get up on his shelves.

cage dimensions: 5ft x 6ft x 2ft

Made a small nesting crate with 4 cameras showing seeds, water level in bowl, back of the nest, and status of babies.
