looking pretty sweet Ascension. As for the mountains i think they look great individually but indeed together the ranges dont seem natural. they look like a collection of peaks and not like an "interconnected range". so maybe you can try to link peaks more by using shading and more complexe shapes as torstan picted above. Also maybe more variation in range-width and more branches may help. mountains take ages to create (so unless you're god it probs will take more then 7 days Still in general I really like where this is going. cheers
