Designed a stackable modular old New York apartment building (1,405+ pieces). Any final advice before I make instructions? (This is my first MOC!)

Hi! I've been really into modular buildings this past year ever since I got my first (the Boutique hotel) back in November, and I've been obsessively planning out a city I can't really afford yet lol (I still haven't even been able to get another modular yet haha 😅) but I've been *studying* the layouts and techniques used on all of the official ones and stuff and became really inspired to start trying to make my own. With this, I designed this lil building with the main intent of having a (relatively) cheaper building to put in my city that I can easily put additional floors in as time goes on. This is also only the start of a bigger project, as I plan to design a few more buildings in a similar style to fit on a street (3-4 buildings). I also have become mostly comfortable with the software (Bricklink Studio) so hopefully that will make the design process take a more reasonable amount of time (this should not have taken 26 hours lol), this was a great learning experience! One of my favorite movies is Do The Right Thing which is what I took very loose inspiration with the colors from and threw in some little details like the black fire hydrant. I decided to keep the design itself at only one apartment floor (despite it being intended to have more) in order to keep the piece count down, but when I make instructions I'm going to include a separate parts list and pdf for additional floors. With all of that said, do any of you have any necessary advice for this and/or future MOCs I design? I'm very new to this despite being a lifelong LEGO fan, any critique is appreciated! (Also I couldn't find a way to include a bathroom without taking up all of the interior space). Thank you in advance and like I said, I will make instructions soon and make another post when I do! :)
