Sneakers in Progress

I'm continuing to work on this piece and added the ball as another element to the drawing. Next step is to tie the elements together with value and shadow. I have lightened the dark shadows around the sneakers with Polychromos Sky Blue #146 and burnished it with a bristle brush. I am working from a photo of the sneakers and shadows can look darker than in life. I used the same colors of Polychromos pencils on the ball as I used on the sneakers for continuity and composition. 

I still haven't used any white on the piece because I don't want it to smudge but I laid down a base color of Polychromos Cold Gray #1 on the top of the ball for value and will add some darker shadowing around the edges to show a rounding form. I am combining two different photos for this piece so it is a challenge to get values and shadows correct. 

In my last post I forgot to note the colors I used in the insides of the sneakers and they are the same ones I have used on the yellow stripe on the ball: Yellow Ochre 183, Dark Naples Ochre 184, Naples Yellow 185, Cream 102. I used Walnut Brown on the insides of the sneakers but not on the ball.
