Since you are only using 2 masteries I would say you are fine. I'd keep a 2-3 lvl gap so you can be sure to max out the skills you need, depends on your type though. Heuksal (glavie/spear) needs less sp than Bicheon (sword/blade). Also, when you get to a higher lvl (40-50) you can always sp farm a little more if you really need to.
Good luck.
