Starlord - same thing everyone has done with the jacket in terms of cutting it in half. repainted his shirt and pants.
Rocket Raccoon - repaint his suit red
Gamora - sanded down her neck to remove that part of her suit to bare her upper chest. sculpted the collar and lower jacket with buttons and such, as well as sculpting wrinkles of cloth on her arms to give the full jacket effect. fully repainted her suit to match the rest.
Drax - aint nothin done to him, he came fully ready out of package!
