So I have been up since 3:20, wide awake for some unknown reason. Was digging around the ArtRage site getting anxious for version 3 to be released (you need to go and check it out. It's gonna blow your mind!!) and I discovered some people doing work with just the roller brush since a squared off oil brush is not available (yet!). I was inspired enough to open the program and try my hand with it. I like it!
...but that opinion may change after some sleep.
