Powergirl looks really cool with the hair darker like that.
It's really interesting how you cast that shadow. It almost seems like you colored everything the same way and then used a lasso tool of some sort to select the area you wanted in shadow and then applied some sort of filter.... I can't seem to figure out how else you would've done it, but it doesn't seem to me like you would've used two separate palettes for this and painted the parts in shadow separately, as it would've taken too much time.
Am I getting warm here, or am I entirely in the cold as to how you did this?
She's beautiful! I'm impressed as how you can get all Dc girls looking great, and still make them unique(which is always a plus in my book) 'cause eventhough PG is kinda built you still manage her to look nice and "girly". I like that some artists still remember Mark Waid's ideas on how Kryptonian's eyes should look like (from Superman: Birthright) .
