Gonna sound odd, but bare with me here. Skyrim has a pretty expansive color pallet in the core game and across the expansions. You have the lush greens of the forests, the grays of he icy wastes, blues of glaciers and Dwemer ruins, the darkness of dungeons, and the despairish purple of the soul cairn. No real Red areas to broaden the game's visual variety to full potential. The only Red area is that hollow where you do the Hircine quest, and that's only temporary. Would love to see some red soaked areas in Dragonborn, perhaps some magma flowing through caves. That would be so choice. As it stands, Solsthiem looks far too much like Skyrim. Some volcanic subterranean areas would do the game wonders in terms of differentiating itself.
