There are 22 videos on his Deviant Art page all in their own area here:
http://stevensanchez.deviantart.com/gallery/#TUTORIAL-VIDSIt is actually 19 tutorials, 3 of them come in 2 parts.
I have watched about 4 of them so far and decided to post a recommendation here while I remembered.
It's not only facinating to watch, it's astonishing. The man sketches stuff in minutes and you can see something evolve in literally mere seconds.
I am not an artist, and I am finding what I have seen so far both educational, and inspiring. I recommend it also to the more advanced artists of our community. Some may be old hat to you art savvy folks, but I suspect you will find something to learn as well and perhaps be inspired as I have.
Sanchez's scary fast sketching actually makes me curious as to how fast some of the resident artists are. Off the top of my head, I'll guess Rex, and DCM of whom I can say from personal experience of several years ago flabber-gasted me with how fast he did something while we discussed it in emails. I'm guessing Wreckshop too, though he's not really active here. So who here is scary fast and still good?
