I'm always torn when I see stuff link this.

On one hand, I applaud the effort to create anything full size that runs and appears to be at first glance a Panther or Tiger.

On the other hand, I'm usually disappointed afterwards how it misses the mark.

Got to keep in mind, we are a statistical anomaly when it comes to the population that would spot the differences and if one showed up in the distance in a film, I would enjoy it. Those are light years ahead of 'paint those Pattons some sort of sandy color and throw a Balkenkruz on 'em and have them roll towards G C Scott' type that we've be treated to in the past.
