Movie Poster Style Graphics Tshirt

I have a tshirt design idea am I am looking to work with a graphic designer that has experience with doing movie poster style graphics:

Step 1: Click the link below and view the illustration style (i.e multiple faces in a group)

Step 2: View the attachment illustration of military revolutionary figures

The goal is to recreate the figures in the attachment into a movie style poster and put it on a mockup shirt
