Just started skyrim a few days ago... Any advice

Topic title should be pretty self explanatory. My character is a breton, I am currently thane of whiterun ( i think thats the name) and a member of the companions. So far I am primarily using conjurations/necromancy, coupled with either dual destruction or destruction and a sword, plus heavy armor. I am currently level 14 but i have only taken perks that I wanted no matter what I speciallized in, so I can easily change my style. What do you think i should primarily specialize in, should i go stormcloak or imperial, should i run around murdering entire cities as a werewolf or vampire, etc.

well, im a level 42 argonian. I specialize in sneak, smithing, one handed, light armor, and archery. I can kill most things in one hit from afar, with the exception of mammoths, giants, etc. It makes the game quite boring really xD. So specialize something that you think is fun and challenging, and not inta-kill from afar.
