I agree that the whole frontage need re modelling, I'd get rid of that strange walled planted area and turn that whole space in to a pedestrian zone/bike park with a better area for the coffee stand and ticket machines, then to the car park area to the left can be improved with a safe dropping off area. It should favour pedestrians though. Most passengers who use Forest Hill station arrive and leave on foot, of course there will be people with heavy luggage or mobility issues who need to be dropped off but dropping people off just to the left is fine in my view. There are very very few stations where people can be dropped off right outside the entrance. Often these areas are reserved for taxi ranks or buses.
