Too D&D and kinda redundant. Keep Str, dex, Int, and char. Appearance should only be a stat in games where it will be relevant enough worth making it. And really it's better served by being some sort of advantage to give modifiers when relevant. 

Most rpgs today that I have seem to split skills and traits into like a tripartite of: physical, mental, and social. And I don't see anything wrong with going with that design choice. 

Anyway for the basics it should be roll over with dice plus stat&trait. Skill and traits should be capped at different values for default games and only tampered to fit the game mood. We totally need to come up with a difficulty system and range as base dice value goes up to 18 which is something to consider
