Seems a little sketchy..

I've borrowed the term "sketch" from Dr. Steven Specht, a fellow collagist whom I look up to.  In this case, it is used in the context of a quick composition, rather than a literal reference.  Here are two pieces that I took no more than 5-10 minutes to compose.  A third one will be left off of this because it was just didn't make the cut. You win some, you lose some, ect.

"Aviation"

"Research"
