Your skills look pretty good. I would try to get Bleed up to level 10, and max your weapon expertise. The Potion Efficiency skill isn't really needed after you have the battle tower, as it becomes fairly easy to get healing potions when your runner are upgraded. If you do decide to reskill I don't know if I'd reinvest in it, but I wouldn't do so just for this (I had 1 point in this before the battle tower, figured it would help so put 5 in after I reskilled, realized it wasn't really needed, so didn't bother with it the second time I reskilled, near the end of the game). I maxed Lockpick as soon as possible, though there are no locked chests in the Hall of Echoes, so the second time I reskilled I didn't relearn it.

Level 1 of the Healing skill comes in handy, as would level 1 of Evade (further upgrades don't give as good an effect per skill point).
I put 5 skill points into Mana Efficiency after getting the battle tower, just so I could summon the creature and have enough mana left to heal, or whatever, if required. I don't know if that was necessary, but at least early in the fjords it help venturing in to areas with higher level opponents. Playing again (probably a ranger, rather than duel wielding warrior) I'd neglect intelligence more (unless a lot of mana is needed for Exploding Arrows, or something), so would still max Mana Efficiency.
