If you want some concept players, below are some from my current group, along with the hero forge renders of my christmas gift to them.
Unfortunately I can't contribute personally, because I'm DMing and I don't want to ruin the good ones for my players, but I can give up one character: Old Ben - an eldritch knight built to introduce a faction. He's an old protector in a world where magic is prosecuted, and I used the aging rules from 3.5 for his stat line. He'll be an interesting character.
Copy pasta from concept emails from my group:
Race: Drow
Class: Wizard
Alignment: Neutral-Evil
Background: Parents sent me to become an apprentice with a famed necromancer and carry on the evil family name. I applied myself to studying the dark arts, but unfortunately the apple fell a little far from the tree. Evil does not come naturally to me, no matter how hard I try. I want to be bad. But, honestly, I'd rather curl up in a corner with a cup of tea and read about murdering innocents to feed my demon thralls than actually go through with it.
Personality Traits: There's nothing I like more than a good mystery.
Ideals: The path to power and self-improvement is through knowledge.
Bonds: I promised my family I would do them proud.
Flaws: Most people scream and run when they see a demon. I stop and take notes on its anatomyName: Pigeon
Race: Human
Class: Rogue (Thief)
Alignment: Chaotic Neutral
Background: Raised by the streets, Pigeon learned the art of theft as a means of survival. He found himself to be outstandingly adept at identifying worthy targets and procuring their most valuable asset. Completely self-trained, he has adapted techniques not yet seen by the guilds.
Personality Traits: The first thing I do in a new place is note the locations of everything valuable—or where such things could be hidden.
Ideals: I will do whatever it takes to become wealthy.
Bonds: I align myself with whomever best serves my needs. I will become the greatest thief that ever lived.
Flaws: When faced with a choice between money and my friends, I usually choose the money.
