With these ones, I like how well the person sits with the nature around them, soaked into it. Really like how the strokes all come together, flowing in different directions to create the shape. The lottery of colour weaved and winding a figure out the Earth (like a wave out the ocean). I think the lack of detail on the faces especially adds to this too - no real personal distinction, its just a person in some shape, just as you may paint a flower arching in some shape.
This is probably the best example:
This one especially, the face kinda rises out of the foliage. The darkened outlines too on his knees and his right shoulder lean him outwards too and give him a slight distinction.
