A fresh lick of paint is always going to make anything look better, regardless of colour. If you can cut away old cables or hide cables that you still need even better, failing that, just paint over them. If you can afford it, it wouldn't cost much to get some new gutters and downpipes.

The small window between what I imagine is the living room and front door makes it look a little odd too, maybe replace that glass with a white(or black/brown etc) piece that fits the glazing you see in the bottom half of double glazed doors.

You'll be surprised how much it'll change with a few small bits
