Oh it's already way better!
As PP have said your inner door is strangely prominent and looks uninviting somehow if you don't mind me saying! Is the interior of the porch uncovered brick? If so, maybe consider painting that the same colour as the pebble dash? It looks like it doesn't know whether to be part of 'inside' or part of 'outside'!
While you're pressure-washing the drive (as already suggested), it might be worth also pressure washing the roof tiles above the porch too - I think it would make the whole building look a bit more loved. Have they gone mossy? (Difficult to tell from the pictures.)
Yes to lighting (needn't be elaborate or expensive), yes to a house number (ditto), yes to venetian blinds or similar.
We painted our pebble dash using a ladder, NP. However be warned, masonry paint is horrid stuff and just seems to get everywhere (and then takes days to get off your hands and arms), and you probably can't use paint rollers because they don't get into all the nooks and crannies between the pebbles. I ruined several sets of old clothes doing that job, though we had a much bigger area to get through (front, back and side of a house which is pretty much 100% pebble dash). It's worth it though, the house looks so much fresher for it.
Will check back on further progress! Bonne chance!
