#2 & 3. Get closer. Ask yourself, what is it that draws you to the subject, focus on that. Example in #2, the scaffold doesn't add much to the pic so I'd have walked up to the love graffiti part and composed the love, part of window, and turquoise siding inside the frame, probably portrait oriented. #3, I would have got close and shot the girl with the words it pours in the frame, probably not even included the whole pic of the girl, just enough to let the viewer know, landscape oriented
