Thanks, Ravells, Hohum. I lucked out with these shapes. Who knew that a chipped garage floor could provide so many hours of fun? I'm enjoying the process and it's a testament to RobA's capability that a novice such as myself can generate a map that looks pretty decent the first time out. One issue that's bugging me some is the dirt layer. I'd prefer to see a more even distribution with more mottled color akin to the manner of the grass layer. I may go back and try repeating the grass layer steps only with colors for dirt. From there I could apply a gentle blur and/or drop opacity to blend the two layers together for something I'm more comfortable with.
