I did this about two years ago when I first moved to Las Vegas. I made no plans in terms of composition; I started in one corner, fitting each piece together like a puzzle or quilt, almost "weaving" it all together like a tapestry.
Here I was inspired by the shapes and colors of sea creatures. There is an endless supply of inspiration there! I worked in the same way - the scene unfolded as I went along.
Here I was exploring the power of two contrasting colors and values.
This was my latest one. You can't see, but there is a portrait of Buzz, our English bulldog on the right hand side. ;)
