Yigal Ozeri's Website
Yes, that is an oil painting--it looks so photographic partly because it's so reduced from the original. If you go visit the artist's website, here , you can see on the splash page a painting that looks a bit more like what you would expect a (very tight, controlled) oil painting would look like. You can see a bit of the artist's "hand" in how the hair strokes go. I am a big fan of his, I also love his color sense! The website is a pleasure to visit and mostly work-safe.
