Character rendering and lighting

Hi, I am struggling to figure out how to shade my character and his clothes especially with the color black that I used for the jacket. I haven't really decided on a light source, but ideally it's coming from the left side of him. Considering the materials as well I wanted it to be a cloth like material for the jacket and regular jeans. I would appreciate any help and input on this thanks.

Storyboard

I've tried to convey a pretty complex story with this storyboard. I was wondering if the story is readable enough to understand the plot where a boy who has left home has found a new way to cope with the absence of his family.

Plein Air Oil Painting

It feels more impressionist than I was intentionally going for. How do I get more real feeling textures in the water and the sand and the trees etc?

Don Quixote

Here is with the feedback i was given. I tried making the feather more interesting and resting the spear against him. I also tried the armor a more 3D look. I kept the attitude because this iteration is supposed to be smug . I tried fixing the prespective problems too, I hope it reads better and i will keep at it. Thanks everyone,
