Track plan opinions and suggestions

I'm looking for some opinions and advice on this layout design. I've attached the SCARM file and also a sketch of the space I have to work with. I'll be using Gargraves 3R phantom track. This layout will also include Legacy and DCS with Wifi capability. I'm not yet a pro with SCARM so I had some difficulty designing the lower level which is highlighted with red track. I know these types of topics are difficult because its a matter of personal preference but I would really appreciate any feedback before I spend the money on turnouts and curves. I'm not big on operating accessories so this layout was going to be more small rural areas, mountains, tunnels. I did want to include some industry like logging, mining, freight loading and unloading, maybe small passenger stations. I feel that with this design I may struggle to find places for them? I also haven't picked a good spot for some type of shelf or control panel to place the transformers and remotes. Please let me know your thoughts. Thanks
