Awkward thumb bend (freestyle looks terrible)

Hello! I am having terrible deformations for a thumb (it’s holding a bow). I’ve tried all sorts of different weight paint combinations, adding vertices, and so on and so forth. But for the life of me, I can’t seem to get this thumb to look good when rendered with freestyle. I’ll attach photos as well as the blend file for anyone who sees a good solution. Thank you!

For those of you that are curious, I have fixed the problem. All I needed was a subsurface modifier, and it seems to have fixed the freestyle issue. I left the preview at 0 so I could weight paint and move bones without any lag, and left the render at 2.
