Probably something similar? I don't see why not.

I don't look at that kind of artwork all that much, but Rutkowski's pictures seem to have a very D&D/Tolkien-ish quality to me, to put it in some words. I'm pretty sure other artists made works in similar styles.

I do recall purchasing a poster with a similar look around 20 years ago, when he'd have been 14-ish. He might be a prominent artist in the genre now, but he's far from the first or that unique.
