Lighting is a problem for me

Hello guys and gals
I’m having problems making lighting right with a rendered image. I have tried all kinds of mixed lighting controls and I am not getting the results it should be. I have a drawing if anyone wants to give it a shot. Otherwise I am stuck.

Where’s your drawing?

How do I upload it. I don’t see an option here?

Do you have an email I can send it to you???
