When I build I usually make a rough version of the complete build first to make sure everything fits well and is scaled nicely.
Don’t get too worried about detail at this point, if you put too much work into it and realize later that you need to change something major it means a lot of wasted work.
Just on a personal note, this seems like a very intricate staircase for a grill entrance.
Some different colors would be nice, like shrubbery and potentially even a small water-related object. Your entrance is mostly grey so I might recommend changing around the colors just slightly and maybe even changing the material to something else.
Don’t worry, I also started building roughly and badly, but after some practice, I started building better! I can help you with your group and also I can help build your place more better! Stay home, Stay safe
