I feel we had this discussion before.
The geography in Skyrim is quite diverse, even if it may look the same because it's all wintry. You had the highlands of the Reach, the autumnal forests around Riften, tundras, hot springs, both leaf and pine forests, and snowy wastelands, all modelled after realistic geography. I thought it was pretty sweet. It doesn't feel as outerworldly as Morrowind, but I think every hold did have its own feel to it.
The only thing that bothers me about Skyrim is that the towns are so small and uninteresting. Oddly enough, Elder Scrolls Online is the game that nails this, as each capital is a metropolis with tons of life and own character. Sentinel and any of the Elven cities are quite magnificent.
