My friend, maybe we turn the table now and you explain how you managed it to come so close! :-)) I tried it out with much worse results. Ok, i am not the worlds best map expert i guess but if you explain what you did we all can check where the "unsharpness" is. BTW, very ambitient to do it in one go. I would have done probably 2-3 terrains to get that result!
