Working in one style and sticking with it has never been something that I have been able to do.  I figure part of it comes from my influence from Push Pin Studio which blew me away by back in the early 70's. So many styles and approaches! They were a group but I was only one guy. Consequently my bag of tricks grew to include a few styles some of which lay dormant a while until they are called for.
I presently find myself working on a couple projects in a style I haven't played with for almost a decade and it is like seeing an old friend after a long absence.
