First and foremost, it's not important what I want, but more important is what you want. Route creation should be fun and if you're happy with it, then that's fine. What you need to understand is that if you want to upload it so that other members will download it and enjoy it as much as you, then they need to see some value in it. One of the things that makes it of value for download is realism. Ask yourself a question. Do your screenshots look realistic? Do they resemble the landscape that you're trying to recreate? If the answer is yes, then you're well on your way. If not, then just keep experimenting until you get there.
In my opinion, I don't recall seeing any actual landscape that looks like the screenshots that you've posted. What are all of those textures supposed to be representing? Don't take this the wrong way, but it looks like you're just picking textures and applying them to get a varied landscape look with no reasoning behind it, but it isn't working. You're headed in the right direction, but you're application of the different textures is too broad. You need to create in smaller blocks and then expand your technique. What I usually do is develop a base texture in maybe 100 meter by 100 meter blocks and then use cut and paste to duplicate the look to get my base texture. After that, I can go in and start adding texture details. Areas as large as you're trying to model can take days, if not weeks, to model and texture and you seem to be trying to do it in hours or even minutes. It doesn't work that way, I've worked for weeks at a time to get landscaping to my liking on a route, and I'm talking about just the landscaping which doesn't include the trackwork or scenery items. You're headed in the right direction, but you need to start thinking smaller in your scale and then expanding out. You seem to have missed the keyword in some of my posts......PATIENCE.
Also, it looks like you have a 20 to 40 ft embankment on each side of the roadbed, but I can't figure out why. Is there a reason that the embankment is so pronounced? I've seen roadbeds before with embankments that high, but it's generally been through wetlands and swamps where the roadbed had to be built up to get out of the wetlands. What is the purpose for it in your screenshots?
