We can already name stockpiles, maybe displaying the stockpile's name on screen wouldn't be a bad idea. Kinda like Prison Architect, but that game goes with a whole "floor plan" kind of art style and this wouldn't work with very small stockpiles:
Problem about icons is that they don't work well with custom stockpiles and it could be confusing to tell what is just an icon of an item and what is an actual item.
Exactly what I had in mind when the suggestion came! (Didn't play Prison Archtect long enough to get used to all stuff hehehe)
And yeah, now you said it would be a little confuse to distinguish if it is an item on the ground or just the icon of the stockpile itself. The color kindda do the trick here, since the item icon displayed have the same brownish color-grade pattern for all "stockpiles-icon".
Didn't fully undestand what Cruxador said about the difficulties to change the color at will, but hope Meph and Mayday have something in mind about it.
So... I had a try at ramps myself.
Oh!! They are smooth! And also kindda short! My thing with the ramps from the beggining was because they lookd like were leading way too far from the ground, almost like a "isometric" view, like the walls on Tibia Online:
Nothing against the visual, just doesn't felt right since the idea is not a isometric view, just a top-down one.
But! Since you shown those shortned versions, its possible to maintain that way?
well it's certainly come a long ways from the reveal ramps
Edit: I do prefer the round-corners that Mayday displayed with the bottom smooth slopes that Meph made.
About the trees.. well as the z-levels goes up the game tend to shown not only the trunk but also the branches and not tend to be just a round top. Yes, I've read that this is just a mockup, but I wanted to do this heads up since the view of highest levels would be not that simple. I guess... Overall, it looks like the Zelda: Link to the Past and its fine heheheh.
Oh! Almost forgot
The beehives... well the boxes would be also nice, but for the sake of representation the medieval its for the best.
And for the floodgates, actually o do like more the real floodgate, resembling an elevate door with chains.
I mean, it's not a construction made on the place, it's a structure that can be carried.
