Super awesome. Perhaps unsurprisingly the rocks look like smaller Herge mountains to me, I'm not sure if it is an intentional move, but I like it. Many of the things I like in this are similar in trait. You've said before that the drawing tends to happen without a lot of thought, just sketch in pencil until it looks ok, but colour detail continues to improve. Small additions like yellows and greens in the water, blues and greens in the dirt, browns in the grass. It's not just more life like, and not just more realistic, its giving a real depth to the world you create every time you draw, and it's getting to be spectacular.
