As artists, it's easy sometimes to settle into a subject you know and enjoy painting because it is familiar to you, but let me challenge you to give yourself permission to explore periodically. You may be surprised at the treasures that are exposed. Stretching yourself to press on to uncharted territories can be a scary adventure but how would you ever find what truly moves you unless you search for it and explore your passion. As Mark says, "if you stay true to yourself and pursue your own artistic passion and your own artistic vision, that honesty will come through to a collector".
Slickhorn NerwbornMark is a western watercolor artist whose own passion is painting the spirit and independence of the modern day cowboy, which he has an abundance of admiration and respect for. I first saw Mark's work at a gallery in Santa Fe, New Mexico about 5 years ago and have been an admirer of his art ever since. Not long ago I stumbled onto his blog where he freely shares his knowledge and expertise on everything from watercolor to wild hogs and wise cowboys.
I encourage you to check out Mark's site. Whatever direction your creativity leans you are sure to be greatly informed and truly inspired.
