Blue Tonal Study

I decided to continue with the colors I had selected for my last painting Blue Complimentary-Analogous Color Study. But as I progressed I worked more toward keying on blue and using colors with blue as opposed to including them as separate tonal explorations in the same painting. I think the next tonal study I need ensure more than one color is explored. This "blue" study is very boring.

Color palette included:
Primary Blue
Cadmium Orange Hue
Primary Yellow
Naphthol Crimson
Mars Black
Titanium White
