I have just realised that your guys look radically different because they don't have cloaks, perhaps your next concepts could include those? I think most people would have worn them on guard duty to keep warm while not moving. I think the GW ones are a bit too puffy normally.
I'm not really a fan of poleaxes in generally (i find they usually look a bit stupid), so maybe that is my hesitation, but I'm not really sure that a poleaxe is suitable for Dale/Esgaroth. They would be unlikely to come across enemy cavalry so probably wouldn't have developed them for battle. IMO, they would have used a pole weapon (spear,poleaxe, whatever) on guard duty at the palace or gates but it would be mostly for show and not for practical use. As the poleaxe lacks beauty for me, i'd be more inclined to give them spears.
I do like that spear design, very similar to the wood elves, but I'd like to see a bit more culture in it. My suggestions would be to have the tip however you want it, but the crossbar part to be more practical looking and less artistic and leafy like an elf one. Try drawing 2 small pennants on either side which hang down to see what you think. I'd probably leave the tips of the crossbar either flat or rounded off like they would have gold rims or something which makes them showy for guard duty and showing off to visitors, but practical enough and different to the old "tie the flag to the pole" thing you often see.
Maybe the actual Dale/Esgaroth helm as made by Weta would be suitable as a palace guard outfit or something? Anyway, those are my thoughts, I hope they are helpful.
Oh one last thing, the mail shirt/chest plate - if they are already wearing mail underneath, they probably wouldn't wear it over the top as well. I'd be more inclined to put a tabard over the top with some nice filigree or design on it. It certainly adds something by having it there though, so good job picking up on that
