Thanks all for the nice comments on the paint up. he has real strands of hair, I will post some more pictures later!
For the body, I did a few things.
1) I modded the iminime shirt so it sits open more by cutting the velcro shorter.
2) I transferred him to a Hot Toys advance, wider shoulders and biceps that filled him out a bit.The jacket sits better now
3) added a bit of belly padding with cotton ball to the stomach
4) Padded up his shoulders and biceps a bit more so make the jacket look even better, Used first aid tape for this, use that stuff all the time on my figures
5) glued the collar of the jacket down and added a thin wire to hold the shape
