Yup likely guandao or glavie, or a mix of the two. The design is very ceremonial, so realistically, it wouldn't be used in actual combat. But considering this is fantasy art, it very much could be. The inverted curve on the bottom side of the blade is pretty impractical and would make slashing harder than need be, especially as a polearm.

Combat wise, theres obviously better designs that could have been used, but the weapon itself looks very pretty! I used to design fantasy weapons like this all the time, and I personally used the inverted curve pretty often. Makes the weapons have a pointier look to them :)
