First, measure your clothes to determine how much short. medium and long hanging space you need. Rather than one set of drawers under the hanging rods, have a stack of drawers. Instead of bifold doors, have double doors. You can mirror the inside and use both doors to get a good look at your front and back. Here's an example of a closet with double doors. These doors are very wide. I have 18" wide doors, for a 36" wide opening, which is plenty. Inexpensive door mirrors are around 14-16" wide and 60" long, so they can fit easily on the inside of the closet door.

Basics of closet design, if you see the wall behind, there is room to store vertically. Good news: There is a lot of unused space in the closet. A lot of potential. With a closet system, there will be so much more function & storage space. I have design closets for 15+ years. I suggest getting a local closet company for an estimate. Probably can send the layout & get 2-3 estimates. I prefer the hanging systems to keep the option of touching floor or not. That way, if I do not want to touch floor, things can still be store under hang if need be. Make sure the shelving is adjustable, because life adjusts & so does stuff. Make the shelving in the corner deeper. Avoid wire. Things fall through wire & it's just not as good for so many reasons. Watch out for long planks ordered online, I tried, but often the material would come in warped, damaged, etc. I also have done wood, getting the holes to make adjustable shelving is no fun. It was more of a pain & took too long & did not turn out as nice. That's why I prefer using local closet companies who provide the material. Hanging systems need to be secured into studs & there are general rules in widths, so shelving does not warp. I love well functional, adjustable closets. Once you have one, you'll just wish you had one sooner:) slat wall example of gadgets that would be useful to your particular items. or get some white shelving with hooks

I like the placement of the walk-in. It's convenient from both the bedroom and the bathroom but it is in neither. That's really great. You can do much better than hanging rods all along the perimeter though. Maybe shelves on the top and bottom walls and hanging rods on left and right walls if you need to hang that much. Or shelves on the top, hanging on the left, a chair in the bottom right corner with a bachelor's chest with a lamp on it and a mirror hanging above it by the door for storage of underwear and socks. I also like the toilet room at the front of the bathroom so you don't have to walk through the whole room every time you need to go. You'll access that about five times as often as the shower so that's a good choice. I would put the door on the short wall across from the toilet though. It makes no sense to have it open right where someone might be standing at the sink. And some of the convenience is lost by having to make a 90 degree turn to access it. Have it open out just in case. If someone falls or is crouched down getting sick, you'll want access. Two vanities is nice. All told this is the nicest ensuite-WIC layout I've seen posted.

I honestly would just do white and good LED 4000K lighting so what you put together will look the same outside .
