Tutorial Tips: Captain America Civil War and half faces

So this is a Daniel original so if you want to draw something like this here are some tips

Okay here are some tips

1. Draw both sides of the head together. Meaning when you are drawing Captain America's eye draw Iron Man's eye. It gives you a pretty even level
2. They do not have to be the exact same size: So if you are drawing one of these with hair one of their hairstyles might be bigger they don't have to line up perfectly. 
3. Make the differences distinct. So I emphasized things like the A in Captain America's mask and the wings because those are things Iron Man doesn't have. 
4. Just go with it: This is something that you just have to try and see what happens

Have fun drawing
