Those aren't ram horns they're http://www.bethblog.com/index.php/2011/11/03/new-skyrim-avatar-items-and-premium-theme-now-xbox-live/ and I like it.
That link does not imply that those horns are actually dragon bone. The dragon bone armor and helm are on the avatar on the far right.
In response to OP, I don't know how you can even talk about not liking the main Dovahkiin helm, and at the same time have fond memories of Fin Gleam. I think the swim out near Anvil to pick up Fin Gleam was always my first stop after leaving the sewers, but GEEZ was that thing ugly! I always hated the fact that it was Glass armor (which I felt was particularly hideous in Oblivion), and looked totally out of place on my stealthy thief character.... Thank goodness first-person let me pretend it wasn't there
