My god D00D, you really need to stop giving peoples first maps bad ratings without any explanation for it or giving any tips for improvement. I've seen this like 5 or 6 times now, and I feel it's a surefire way to kill someone's motivation and esteem.
Anywho, I think this is a really solid first map! I think it's really charming how you tried to go for the theme change halfway through, like many modern sonic maps do. However, the map is FAR too cramped to work as a Modern Sonic map. Boost formula thrives on open areas with quick obstacles that you can see coming. The map suddenly becomes very frustrating and unfair when you can't SEE. Fortunately, this can be remedied by just... enlarging your map. So much is fixed just by simply multiplying the play area x2

There's also another issue I noticed, although a bit more subtle.
Your nature areas are drawn SUPER blocky

...and your industrial areas are drawn SUPER organic

This is an error I see in a lot of beginner maps. You should try to build around the material itself! More rocky textures suit themselves to more organically drawn walls, while more blocky textures suit themselves to more geometrically drawn walls.
Anywho, I hope you take these criticisms to mind when creating future maps (if D00D down there hasn't dissuaded you), to create something more enjoyable. This is a really good first attempt. I might take a shot at a modern sonic level myself seeing as others are trying it. I may be able to pave the ground in which other levels can follow, or something along those lines (I swear I'm not trying to be egotistical :V)
