Starting a new character just to try something new. Gonna be an axe and shield warrior. Just want help deciding whether I should do the typical heroic Nord, an outcast loner type of Orc, or just be a Breton for their spell resistance which will be useful?

Cheers.

Orc. My orc is a freaking badass.

Got bored but that is me, it is a good class however I found it limited due to the attraction to daggers/bows/magic. In the end go with what you want, personally I would be a mage, for some reason they seem to fit the character pretty well.

I went orc this time around, I used a nord in oblivion but Nord seemed to be to run of the mill seeing as its set in the homeland.
Besides berserker rage is a really nice perk when you come across the hard fights.

If you're not RPing Redguard and Orc would be considered best for their powers. RPing and going with a Nord for the civil war is always fun. But really just choose what you think looks best. No real differences besides asthetics and minial starting bonuses.

I made a Nord Warrior ala "Thor" it's been pretty fun....need a bow for dragons though.

This isn't on your list, but I started as a redguard pure melee, it's the only character I've played on skyrim, at level 30 I still enjoy playing it - The resistance to poison is pretty useful considering I get supposedly poisened alot

Up to you. As an orc you can enter orc strongholds, but you have to prove yourself to go into nord cities which can be a pain. I did orc in Oblivion and Nord in V. I like how the Nord looks in heavy armor.
