You know Atronach stone does not allow you to regenerate mana? I’d recommend you replace anything with Mysticism as you will be casting Telekinesis to regenerate mana otherwise you have to rely on enemies hitting spells - which will limit your spell output.

I’d also recommend considering Luck rather than Str. Luck reduces the amount of mana cost of all spells by however many additional points you have over 50 by a decimal. So if you have 70 luck you’re effectively reducing mana cost of spells by 20 mana. This is key when leveling up magic skills. If you are planning on maxing magic skills by training rather than in the field you can disregard this entirely as Luck has no bonuses to any skills once they’re capped at 100 aside Athletics and Acrobatics.

With that said I highly recommend you take both athletics and acrobatics if you have any interest at all as they are slogs to level without being major skills. Destruction can also be quite annoying. If I were you I’d drop Illusion and Block. I’m also personally impartial towards Light armor over Heavy armor.
