I must agree the shoulders look like they're popped out of socket atm, and they have this square-ish shape to them. Like i said before, I'd move them closer to the middle a bit, and make them a bit rounder.
The proportions have been bugging me quite a bit, I know brolly is meant to be crazy huge, but something just doesn't sit right with me. I think I know now what it is, after lookin at a few refs, I think everything between the top of the waist/belt/cloth area and the bit between his boots is too small, if you make his hips/pants a bigger just a tad (move the boots along with it, they're the right size though, cept maybe make the top of them a little bit thinner) it'd make a lot more sense. I can see that you're going for waistline/shoulder contrast ratio, but it looks a bit like his lower half is a different build from his upper half, there's a lack of unity in it.
That being said, its a major improvement, but as you and I have discussed, something bugs me about the proportions.
