warming up with a new material

Whenever I take a break from painting and drawing, (and these breaks are always about making space for something else - in this case a family holiday and experiments in plastic), I always find it difficult to begin again.  I can't remember where I left off, what I was thinking.  This time I took a look at what I'd been doing and the barrier was that I wanted a bit of time to warm up before entering into that space because I liked some of the beginnings. I have never really used oil pastels, preferring chalk, and I wondered whether using an unfamiliar material would result in something different. This 16 X 24 cm drawing is a response to one of my unfinished paintings.
