Lonely tree protecting a stone-made house

I am looking for comments on the composition of this picture... Since

I am studying photography now, I would welcome all comments. Thank you

in advance.

This photo is simple but striking. I like how the view continues up into the empty sky. I think a little more vibrancy in the colours would give it more of a lift. Another idea might be to take the same photo a number of times in different seasons or different times of the day.
