This is an acrylic painting by Hertfordshire artist, Christine Spence, done on Pebeo canvas board. It's either 30x30 or 40x40.
Once a month or so, a few of us meet together in Essendon for an art workshop with her. Essentially, it is a watercolour workshop but she covers everything from design, composition and drawing through to painting. Throughout the year, she covers dry media (pencil, charcoal, pastels, etc.) and wet media (watercolour, inks, acrylic, oils, etc.) as well as concepts and techniques. She runs three-day summer schools each year which allows you to immerse yourself in art for three solid days. (Warning: includes homework! LOL!)
I first joined the group about 15 years ago, although I had a four-year gap due to a job that required me to work every Saturday. Some have attended even longer than I have but new faces are always welcome. Although we work hard (as it's a workshop, rather than an art club), her studio at Flint Stable has become a monthly sanctuary from the hustle and bustle of life! Thanks Christine!
(Yep! That was an unashamed plug for our teacher! Hope you don't mind.)
