Insightful
When I saw this flashs page ( the one i'm writing this review on) my first impressions were "*sigh* not another perspective tutorial"., expecting to see a box drawn in 3 point perspective.
But I was wrong, I hadn't really known to much about perspective beforehand, only really the knowledge of drawing 1,2 and 3 point. You gave me a real insight into the workings of perspective.
Great job, 87/100 A+
