nice
you should stick to teaching scripts, your blood tutorial is just bad... your colors arent realistic, and that effect would only work if it was blood sitting on a log, blood doesnt drip unless it has something to drip off of, and blood splatters according to how its applied... without an object to apply it to you cant really have a tutorial about blood... maybe on how the color of blood is... and that was too red.... its usually darker... none the less, your a great programmer, and should push thta edge, or get some education in drawing/art before you attempt to teach it.
