Roamer and Cassie Together - Large Scale Sketch

This COULD be one of my better sketches of Roamer the Golden Retriever, or one of my worst, depending on how you look at my previous artwork.
Because of the larger piece of paper I'm using here, his head is pretty well balanced with his hair and ears, but his neck is slightly too thin, and his body is slightly too slender. It just looks weird. And that always happened when I tried drawing on 12x18 inch paper rather than 8x11 inch. Thankfully that doesn't happen anymore.

By the way, Cassie the Flea's hair there, looks like one of those lumpy dinner rolls rather than curls.
