That's Art, capital A. I like the texture of the brushstrokes throughout the painting, the composition is good, the values and their contrast work well with the composition, and the subject is just plain weird and cool in the good way--folktale creatures that look wrinkly, gnarled, sinewy, real.
Only two critiques I have are the lack of a shadow for the big guy, and the perspective of the path the big guy is standing on looks slightly off, too steep. The angle of the path could be shallower, it looks like it's at a 45-degree angle right now. 35 to 30 degrees would be better IMO. That aside, fantastic work.
