As you are only looking for ideas perhaps a starting point would be a modern, square style of entrance that you could get ideas from. I couldn't find what I wanted exactly for a photo, but I think if you took points from this photo and adjust to your budget it might suit?? Eg. I think if you can get a nice wide door with a bit of glass on either side, it would really present well. Raising the height of the concrete at the front door with decking tiles or stone tiles depending on your style could really enhance. Concrete pavers you could even make yourself! They can be smaller or larger and if scaled right to the proportions of the house can make it a little more formal. As you have the driveway on the side, I would put a screen on the left and emphasise the left column making a feature of it as in the picture. The column on the right does not align with the entrance, I would not emphasise that column? But perhaps hard to gauge from one photo. If you went for wood this might be an idea.

I love Julie's ideas of succulents , especially the pics with several different ones in the same pot . As far as the grey , I wouldn't -- you look like you like colour and excitement , so I'd go yellow on the pots -- a similar or slightly brighter shade then the cushion on the couch or chair to the left . It would tie it all in , and make that lovely mat look more like a feature too IMO . Without knowing 'the bigger picture' ( what else is 'happening' around that wall ) , just what I see I'd be inclined to add a light either side of the door too -- stick to the same shade as the joinery ( personally , I'd go for a 'clean rustic; style with say 15 squares each side ) , or if brave ( and assuming the guttering etc is probably a similar charcoal as your door joinery ? ) , go for the same yellow as your pots -- add a Wow !

You could try Wet & Forget on the driveway. You can buy it ready to use and attach it to a hose or buy a bottle that you dilute to use in a sprayer. I have used it and it works - slower than water blasting but it won’t damage driveway if it has some damage? I can’t quite tell from photo if that’s grass clippings/mulch or broken concrete on driveway? If you use it be careful not to spray garden bed. I live in FNQ and we planted seaside daisy - doesn’t need watering but it also won’t die from our wet season. It’s a ground over and spreads out beautifully in a courtyard area that’s get a lot of sun. Just needs a trim from time to time. I see you have Rio (purple green ground cover) which you could separate and plant down the path but it does like water. Maybe for the fence you could try attaching lattice to it and plant another passion fruit vine to help cover the whole fence. It does look like you need to get rid of some woody parts of the passion fruit. It’s a tough plant and will enjoy a bit of pruning. We had one that I thought had died last year and it has returned with no help from me. Be careful with the heliconias and gingers ... they can get out of control if you don’t stay on top of them. Anything tall will cover your fence but it will also cover the passionfruit vine which obviously loves the spot it’s in. Good luck!
