I mailed him yesterday as at the moment the two models he does have are both sold out, but he replied (via e-mail and on his site), that there would be stock again soon as well as a third model.
The scale of these models is listed as being for the 30mm range with the size of the actual models standing around 25mm, making them still a head shorter than most human sized models in any and all armies.
Included below is an image I found on CoolMiniOrNot of the Ulkan wielding the CrushHammer. I personally think it looks awesome. I will include the link to the actual page here.
