I usually don't get into the photoshop business, but it's easier this way in Indy's case.
Here's what I see as wrong and was hoping to see improvements on:
The brevity of my comments might not explain everything; like that the holster is also too large and the wrong shape, or that the shoes didn't really have that large white stitching on top, or that a real braided whip as an idea is cool but the scale makes it look toyish...
I'm fine with the pants and the shirt (which I didn't mention). That's about it really. Everything else, even if you feel it's good enough, is simply inaccurate.
So it isn't JUST the sculpt here. It's a whole array of issues that keep this figure from getting to the level of Sparrow or Joker or Captain American or Superman or Bale Batman...
Even IF they fix the sculpt, this guy still has a lot of 'nits' to pick on.
