All melee builds use the same basic principles. Always try to achieve a good balance of strength and dexterity for the gear you have.
Since it looks like you have 20 stat points still to place, I'd say to do 10 into dext and 10 into strength for now. If you wanted any vitality it should have come in from your first points before you gained any levels.
100+ strength, 75+ dext are what I'd guess to aim for with your current gear and fg funds. If you have any other questions about the game or your characters just let me know.
