I am doing a character. Example, The left or right view when I push the elbow towards the back, on the front view it goes…

I think I figured it out last night. When I am looking at the model sheet in Blender. I did the front view mesh and the mesh was facing front with elbows bent towards the back. But when I would go into to side view of the model sheet the mesh of the character was facing the wrong direction. So I reloaded the model sheets but on the side view I flipped it (Flip H) Horizontally so now all mesh and model sheets are facing as they should. I will still upload some shots just incase I may have done the incorrect fix.
