Jim Thalassoudis gets my vote today as a great local artist. Jim does a lot of work on skies at sunset, a subject that he does an amazing job of.
I recently saw one of his works at the brilliant Exquisite Palette exhibition at St. Lukes.
Be sure to check out Jim's Small Paintings Project, an ongoing project where Jim is going to sell small original paintings via the website, at very affordable prices. If you head over now, you might even get your hands on the first piece on sale (pictured here).
