Welcome to the forum!
I've also played WoW in the past and I think in some ways, the character progression couldn't be farther apart than night and day.
In WoW, most people try to raise their level as quickly as possible and then spend most of the game at their level cap. Most of the quests are a bit boring TBH. In Skyrim, I don't care at all about raising my level, and actually enjoy the lower levels more than higher levels. I don't craft items in order to "win"; rather I craft because I'm playing a tribal shaman who prides himself on concocting dangerous poisons, or a refugee from a savage land who worked as a swordsmith before coming to Skyrim, etc.
It's really more about exploring the world, talking with NPCs, joining factions, watching the story of your character unfold over the course of your playthrough. Everyone's experience is slightly different, and each character is the hero of a very different epic tale.
I have only one suggestion:
Take your time with the game and don't join all the guilds with your first character. You might want to start with doing just one or two of these faction questlines and/or the main quest with your first playthrough. Not only does this improve on the RP experience and help to solidify your character's unique history, but it also saves a lot of great content for future playthroughs.
For example, I had a chance to play four very different characters. My first character was a Dunmer kleptomaniac who would steal everything that wasn't nailed down. He ended up getting caught by guards and thrown in jail very frequently, in all of the Holds except Riften. I had to break out of many different prisons. Focused on stealth, pickpocketing, Alchemy (poison), some archery and the backstab perks. The stealth gameplay in Skyrim is a lot of fun, greatly improved from previous games in the series. I only did Thieves'; Guild faction questline and some smaller, quests as I traveled around the provinces. By the time I reached level 40, I had been playing over 200 hours and decided to start over with a new character. During that time I completed about 70% of the Thieves' Guild quests, collected a few shouts, explored a lot, met some companions, and that's about it.
My second character was an arrogant Nord barbarian who thought sneaking around, using ranged weapons, magic spells / enchanting, etc., was for cowards. You would never catch this guy reading dusty old tomes in a mage's college. No ranged attacks and no sneaking presented a significant challenge on Master difficulty, but it was a lot of fun. I focused almost exclusively on 2-handed, with a little bit of smithing. I put all my points into Stamina, no Health, no armor perks. I did the main quest, as well as the Stormcloaks and Companions questlines and by the time I finished I was at level 27 and had logged about 150 hours.
Third character was a Breton mage, focusing on Destruction and Conjuration, who didn't give a damn about the Civil War and would sooner die than hang out with sweaty warriors in the Companions. She researched the arcane arts and wore no weapons or armor. I got up to level 28 or 29 and I had completed only about 60% of the College of Winterhold, collected a few shouts and that's about it. That took around 180 hours, and I decided to start over and try a playthrough with some survival/hunger/hypothermia mods as well as mods that make the game more challenging at higher levels.
Now I'm playing an Argonian witch doctor who wears some cool looking (but weak) tribal Forsworn armor, focusing on Illusion and Conjuration, as well as throwing knives and throwing poisons (installed a mod for throwing weapons). I plan to complete the College of Winterhold questline with this character, collect some shouts and perhaps do the Bard's College. I never buy spell tomes from merchants, rather I use only the ones I find in dungeons. As a result, finding a spell tome is almost as much fun as finding a new dragon shout, so this enhances the exploration aspect.
At this point, I've already played several hundred hours and there is still a lot of content in the game I haven't even touched. Been saving the Dark Brotherhood for last, and look forward to joining with a Bosmer or Khajiit assassin character during my next playthrough, perhaps I will also complete the Imperial Legion or the Thieves' Guild questlines.
