The jnix sculpt is better than HT imo but I don't think to the degree that others here clearly do. It does look just a bit oversized on the smuggler body to me but looks better on the stormie body.
Have to disagree - it looks great on the main body, not too big if it's adjusted to the right height on the neck. But it does look great on the stormtrooper as well.
The HT sculpt has the elements (and it's slightly improved paint on the new releases). I'm going to let someone try a repaint on it to use on the Hoth Han, but IMO, as great as Jazz's repaint is, it's just not quite there. He faked a little fullness to the lips, but the Jnix sculpt has the right fullness. The philtrum (area between the mouth and the bottom of the nose) is more pronounced as are the laugh lines on the Jnix. The eyes are set too deep on the HT and the jawline is too square and sharp.
I put the HT sculpt on a Max body and I dont think many people could tell you that's Harrison Ford. Jazz improved it for sure. but it's not the same.
I wish everyone who wanted one could get one. I encourage Jnix to do more, but respect his opinion not to. Sadly, everyone who wants something close will be able to get the inevitable recast.
