My Style

I've been giving a lot of thought to my 'style' as a painter and though it keeps evolving as I am introduced to new materials and methods, the work always looks like mine.  Regardless of what subject matter I paint, my main goals are to use a lot of vibrant colour, to simplify form and imagery, and, the thing that I've loved the most for several years is to add pattern using stencils and spray paint.  There is something I absolutely adore about incorporating layers of random patterns.  Early on as a painter I struggled as I wanted to add pattern but wasn't happy with painting it by hand.  It felt laboured and tedious to me instead of being more intuitive and fun, which is why I love spray painting.  My challenge, though, is that I am always concerned about the environment so both the VOC's of the spray and the actual use of spray paint cans that cannot be reused is an issue for me.  One consideration is to try an air brush...I have a friend who uses it and has offered to let me try it.  My concern is that I will lose that raw, rough, splotchy appearance with using something so fine.  Also, I would love to use paints that are both non-toxic, healthy for the environment and professional so that the paintings won't fade or discolour over time.  Any suggestions?
