I don't play Tau myself, though I've always liked the Tau aesthetic. This, to me, looks like the Tau and the Imperial Guard had an engineering baby, so even if I did play Tau, I wouldn't buy it. On the other hand, the model is quite tall, clocking in at 11 cm. Compared to the average battlesuit height of around 5 cm, it would definitely be the tallest Tau mech on the battlefield.
Anyway, I just thought I'd put this up to see if anyone was interested.
