I'm a concept artist in the video games industry starting to dabble in 3D. One thing I've noticed is many 3D artists would like to improve their drawing skills but feel a little intimidated or don't know where to start. I've finally had some free time so I've created a basic "How to Draw" video tutorials on my website that are freely available:
It is a matter of learning to walk before you can run. In subsequent videos I plan to build on the skills here so hopefully in no time at all, people can be improving their sketching / artistic skills which will directly translate back into 3D (composition, dynamics etc). Would be interested to hear what people think.
