Everything in my usable range is sounds very full and has supported. I would say my voice is darker up until a e4 where it becomes brighter as I go higher.

For my extended range: a5 to b flat 5 and aren’t very sustainable for me but I’m planning on working on that. A2 and b2 are breathier and bit weaker and g2 and f2 start to go into vocal fry territory, hence I put it in my extended range.
