In my post of yesterday I mentioned that I could “improve them by adding some shading” but that I was posting the quick sketches ‘raw.’  I’ve had a couple requests, asking me what I meant and/or what I did.  Truth is, there are a lot of things one can do but in this case I kept it very simple.  Here are three of them with some color added.  Doesn’t change things much but it adds a bit of spice I think.
