Cycling Print: Photoshop in-progress 1

This is the initial step into Photoshop where I'll design the print. I first refined the sketch a bit, enlarging the front wheel, adjusting the road, other little tweaks. Then I chose a background color starting point, a warm red, suggesting heat, anger, blood. The next step will be to define the edges and add one or two more colors to the palette. I will also be refining the face with ink line work as well as other details. Not sure about the road, think I prefer the severe straight-edged version over the s-curve. Also not sure how or if the lettering will work its way into the composition.
