Phew, okay, I'll answer in bullet points if that's ok with you.
Playstyle: It's alternating between dual wield One-Handed (which, as mentioned, kills everything in one hit, even Ancient Dragons on master level difficulty) and is thus pretty boring and dual-cast Destruction, which is a LOT of fun, but deals pathetic damage in comparison, though you're equally as untouchable because of the Impact perk (enabling you to stunlock everything). I don't sneak, unless it's quest related, and then I use Muffle & Invisibility from the Illusion school. The points in Restoration are for enhanced magicka regen, increased spell damage against Undead and obviously healing, but that's no longer necessary since about level 60. Alteration is for the 30% magic resist and 30% magic absorb, making me practically immune to spell damage.
Equipment: Legendary Dragonplate Armor (because Daedric looks just silly) and two Ebony War Axes (same base damage as Daedric War Axes, 15, but nicer looking in my opinion), smithed to Legendary with 4 +29% Fortify Smithing enchantments and +130% Fortify Smithing potions and enchanted with a +32% Fortifiy Enchanting potion.
My enchantments are:
+29% Destruction & +72% Magicka Regen on helmet
+29% Destruction & +72% Magicka Regen on chest
+47% One-handed damage & +72 Magicka on gloves
+47% One-handed damage & +72 Stamina on boots
+23% Magic Resist & +29% Destruction on ring and necklace
+81 Fire Damage & +81 Shock damage on both weapons (interesting tid bit: because these are executed by the game as regular Destruction spells and I have >100% Fortfiy Destruction, they don't consume charges, and never have to be recharged with soul gems, they also profit from all spell damage perks and potions)
Skills: Yes, I've leveled everything but Sneak, Pickpocket and Archery to 100, things like Speech, Lockpicking and such came naturally while playing, the only thing I've had to consciously spend time on was Block (requiring me to stand in front of 2 giants for about 20 minutes) and magic skills like Illusion (done by repeatedly casting Rally on a Jarl for about 30 minutes) and Alteration (casting Detect Life and Telekinesis in each hand and taping down both mouse buttons for 15 minutes while getting a shower
).
The points in Illusion are for Aspect of Terror (+10 Fire dmg, +15 with perks) because fire spells have a fear component and Quiet Casting to let me cast anywhere without being detected.
Insects in a Jar: Four so far (two moths, a butterfly and .. a bee I think? not sure)
As for having finished the game, not quite yet, I'm still doing the Dark Brotherhood Quests and the Thieves Guild Quests, and still haven't even started with the Civil War.
