Most of Daniel's work, within the past 5 years, has been accomplished using a "brushless" technique. This is true especially with his more abstract/expressionist pieces. How they are created is a personal secret of his. This is not to say he does not use a paint brush because he does, he just doesn't like to.
If you are interested in purchasing a piece you see (please check availability first), or want to commission a custom piece, please contact Daniels selling agent here..
