You did goodI am a long armer and the best way to learn is just draw them out.Over and over and over.The brain doesn't know the difference between paper and pencil or machine and hands.Try it,it works.I have a lot of scrap paper I draw a lot of stuff out on.It took several weeks to learn Jamie Wallens feathers but now I can feather any block in any shape in no time.Try it.And post your progress.You are off to a good start.
