The execution is very good and the model is easily readable and distinguishable compared to the other Far Seers, however the model looks a bit too similar with the Fel Orc Raider on zoom out, I would recommend splitting the geosets of the three spikes on the mount then UV map them with the Fel Orc Burrow's spikes to give it some extra fel feel. An icon is also needed.
APPROVED, nonetheless.
