The first one is a bit tricky, so let's begin with that. The reason why I don't think it works is that the distance between the middle and upper row of buttons appears too short in relation to the distance between the middle and lower row. The wearer's posture might make this problem look worse than it is, but I don't believe a more relaxed posture would eliminate it. The solution I would suggest is to lower the two bottom rows until the middle row is roughly equidistant from the two others (thereby also lowering the closure of the jacket, which would have the added benefit of making the wearer look less stuffy). (I should mention that one of the resident tailors on here -- I forget whom -- once wrote that the standard practice is actually to make the distance between the middle and upper row ever so slightly longer than the distance between the middle and lower row.) The problem is that this operation would necessitate the jacket being completely recut, which is ... a bit of a hassle. I therefore would just remove the upper row of buttons, which would not be ideal, but still better than the jacket's current look.
The second one I've dabbled with in Photoshop:
In my opinion, the only jackets that look better as 6x1s than 4x1s are ones where the overlap (or "wrap") is very slight. This is not one such jacket, however, and worse, the upper row seems awkwardly placed (but it's a bit hard to tell since there's a lot of pulling going on). Eagle-eyed readers will notice that I took the liberty to move the middle button row on the diagonal. It could be left as is, but I think this look is more pleasing on the eye.
