Two at-will racial powers?
Note that every other race receives only 1 racial power, and they are all encounter powers.
While the powers don't seem overpowered in and of themselves, I would try to rework your template so that it conforms better to the norm. Rework the Swampwalk into a class feature instead of a power, and rework the other one into an encounter power.
Just my 2 coppers.
