You're welcome.

It's hard to "constructively criticise" on a forum because often it sounds a lot harsher than it's intended. Now that you've started, I hope that you'll get the bug and want to make more and more videos!
There are quite a few guys who post a new video every few weeks and you really can see the improvement each time. Please show us your next production!

It doesn't have to be "lighter" but think about using light to create an effect. Even a torch with a bit of tissue paper over it can help to fill in a face in a darkened room.
