An artist, he is not - but I wouldn't be hard on him. Yes, you can nitpick it, but I think the important point is that the basic idea behind the track is the product of a racing fan rather than a technician. There's a definite appeal to that, and I think the end result is going to be really nice.
I wouldn't want this to become a trend, though. It's cool to have one track that brings together some of the great bits of other circuits around the world, but to have more is to risk losing the individuality of each circuit.
That drawing fits to a tee my opinion of Hellmund. Well-meaning and enthusiastic, but also naive and a tad short on self-criticism. (eagerly awaiting the inevitable deconstruction of that little statement)
