Definitely the after. The biggest problems originally were 1) you could barely make out the ramps, and 2) very little height variance, so you couldn't easily see where the ramp was, and had very little idea when the height changed. You managed to pull off two aesthetic problems that each work together, to make something truly incomprehensible. With these changes you're headed in the right direction.
Yeah, now days i'm more experienced with the data editor and triggers, so i want to make a city map with the original idea of Cloud Atlas which was having cars and hover cars wander around in the light roads, but for this one instead of light roads the unpathable ground (level -1) will be very close to the lower pathable level (level 0), so you could see the cars wander around the streets of the lowest level, or at least that's the primary idea for the map's theme :3
Uhmmm.... Guys i need your opinion in something, what are your thoughts in my new custom billboards?
The only problem here is that i don't know if i can use that last one, i probably can, but i'm just not sure, so that's why i'm asking here (yes i read the ToS but still...) I have a few others, but i forgot to screenshot them and i gotta leave now, oh well here, are some other pretty shots.
As for the map itself it still needs a lot of work, as you can see on some of the boundaries of the screenshots.
I think i'll do a competence in Reddit to get more/better billboards, the only ones i can use are the ones that don't have any trademark issue and are simple enough that you can understand them for afar, i suck at picking billboards (i have like four atm) so i think i'll have to go with the contest.
/EDIT// i almost forgot, no sadly you can't make bridges where the units can walk on top and at the bottom at the same time without using a hairy amount of very complex triggers, also, those bridges are as you said in the bounds of the map, but atm i'm trying to get those others working, they are just a touch for the map, and they don't play an important role in the overall theme to keep them at all costs but as i said they are a nice touch.
