week 5 background character line up, coloured model sheet and peer review

I decided to include the rest of her family as additional background characters. i imagined  early on that she's living with her grandparents and little brother Alfie.
Alfie is an interesting background character, i see potential in him to become billie's sidekick when he grows up. Billie the cat and Alfie the owl. Like the owl and the pussycat nonsense poem.
his grandparents design is based on my own grandmother and the guy from Pixars UP.

I added a 3/4 turnaround pose to my concept art board. i was also thinking about taking away the backpack as i feel like it would obstruct her from doing her free funning, gymnastics and arresting the bad guys

I also experimented with slightly different colour schemes. I like the one with the bluer belt and tail.
