Sketch for painting

I do a fair amount of illustrations for Pheasants Forever magazine, this is a sketch for a painting for an upcoming story about hunting in Iowa, its a great story and was fun to come up with the sketches for the story. I use a fun process in Photoshop to do my sketches, I use an overlay layer filled with the color of my choice on a separate layer above the drawing layer, it gives the drawing this nice color that you can't get by just changing the color your drawing with. Anyway, just mixing it up a bit.
