Just a quick update -- still thinking about this map, but life has gotten busy.
Yes, shadows are what I need for depth. I have a few other ideas as well, but those are the really crucial things. The version posted above only has a very minimal omnidirectional shadow; it's basically just there to add some visual contrast between the walls and the floor. I fully intend replacing it.
Aaand here's the latest WIP.
Changes:
- added walls (with shadows) to the perimeter of the pool. Not entirely happy with the result, as the stairs lack anything similar for their sides.
- Removed the inner glow and outer shadow on the walls.
- Put a bevel with a custom contour on the walls.
- Made the whole map dark and added some light. The yellow dots are references for light sources, which will eventually be replaced with some suitable light-emitting props.
- Added a grid.
And now I really have to go to bed.
