I can not find one photo to support my suggestion..but here goes. Dark brown Mansard roof.., think ing the entire house should be that brown. Then I would paint the front door and the storm door green (lawn green).

I think either a porch or an awning would look silly with that roof line, sorry.

Windowbox and more lanscaping under main window?

A porch can be done with a mansard roof line. Trim out the windows on the second floor ... here's an example- of course you would have to modify the porch to fit the layout of the front of your house.

A few more examples with porches. I think making the top floor window pop with thick/decorative trim would make a big difference.
