In a way, it helps me to stay fresh and also provides the opportunity to try something that I was successful at when painting with oil and apply it to my acrylic painting and visa-versa. The result often turns out great (much better than expected) but occasionally it leads to a not-so-wonderful result. When that happens, I have also learned how to recover from a mistake in both mediums. Experimentation is initially a little scary, especially on a large canvas, but ends up being a lot of fun!
I am currently putting the finishing touches on Solomon Bay - 30" x 40" oil on gallery wrap canvas).
And, I am half-way through my acrylic commission seascape painting (an as yet an untitled 24" x 72" acrylic on gallery wrap canvas).
Have a great week and experiment a little!
