After reading EVERYONE state that this helped them out a lot, that this is the best thing since the wheel, that without this they wouldnt be able to draw circles, and that life would cease to exist if Zhanglu hadnt worked his voodoo in this video I felt VERY inclined to give a proper explanation and well thought out response to this video. Unfortunately I dont have time as I am still picking up my jaw from the talent that Zhanglu shows.
All kidding aside, if your looking for something that can be a guide, a motivator and a general knowledge builder then this is probably worth the $20 dollars to you, probably even $40. But what I like just as much as the video is the files that come with it, there are 6 .psd files, 10 .jpg files, and the 1hr 7min video that takes you step by step on not one but 4 portraits (one is much larger and easily viewed to show all the tiny details as they are added).
This site is supposed to be going down sometime later today (its 1am EST here) but I just wanted to let everyone that views this before it does.....this is amazing, and it helps an amazing cause. Well worth the $20.
