hair cold grid experimentation

When looking at making these into grids i was looking at what i thought would work well together, image wise, and thinking of the overall grid.
Thinking about it, i think a 2 x 2 grid would be optimal for this project, i didnt want them overly small, as i wanted to see detail in the way the hair falls and looks, the shapes and patterns it makes.
the obvious and simple  2 x 2 gride focusing on just the darker images to create a connection, here i used one where u can see past the hair and see the background and the shadows but im very unsure about.

i did also concider using a grid with different colour hair but i dont think it looks as impactual as the grid before.

though in all honestly my fave grid here would be the one below, just  a plain and simple grid with all the same colour and it allows u to focus on the hair and the shapes and contoritons its making.
