SOLVED:Arms sunken into body // Fix slot rays makes it worse

So I've been working on this piece of CC for a while now. It's the only one so far where I've had the "sunken arms problem", and it's stressing me out quite a bit.


I've done as much research as I could, but nothing helped. I did the Cats & Dogs batch fix, the fix slot rays ((which made it worse, hence the title)), I even remade it 2 or 3 times. Here's the download link if anyone could help me, thanks. {x}
