I like the character silhouettes, can you work with her hair as well? You might want to show some variations on her hair stylle. For Hooka, try some more on wood material version. For example, hooka has oval shape that is made of wood, try something like he used entire tree stem as a body of hoooka. So it will look like tree stem itself rather than nicely carved oval shape.
Susie, can we do some thumb sketches with marker or pen? seems like you do much better with traditional medium. Got it??
Thumbnail sketches of the queen or the hookah?
