I recently finished the two sketches from the previous post.
Just darkened up the darks a bit, and used white charcoal pencil to “heighten” the very lightest highlights. I decided (probably mistakenly) to ad a bit of color to the Steelers football one.
This is a commemorative 75th anniversary Steelers “mini-helmet” by the way - which is why I have the splash of yellow highlight there. And of course every Steeler fan would know the significance of the numeral on the jersey.
