I just received Daniel's newsletter and included were these pictures which are for sale as Christmas cards. If you're interested, you can get further details from www.danielmitsui.com I like his style very much indeed. It is very refreshing to hear him freely admit that he has areas where he feels he could improve (he says his figure illustrations). I can only pass on advice that was given to me. I was told that skill comes with work. To some it comes easily, some not so easily, but if you work for it, then you'll get there. And, I was told, if you love what you do, you will put in the work.
This is the second feature I have written about Daniel's work (first is here). I am taken with his style and would like to encourage him to keep on getting better and better.
