Fancy things!

Hm, a sewer area is the last I'd want to make. There is so much you can do in it, I'd be constantly feeling I am doing too little. It's also generally hard, it seems, just like the castle-based one. Hope I never need to make one...

Those billboards on the mushrooms look out of place. They would look funny if you were a really far distance away. IMO

Same goes for the water puddle underneath it. The area looks bright enough around it. But that decal shows up really bright in darker areas giving off a weird look if your far away.

Not knocking your suggestions, I appreciate the input, but how do the billboards look funny? The mushrooms are a stylistic choice, I wanted to broaden the color palette of the sewer area a little more, and glowing blue mushrooms have a certain air of mysticism to them, that I found interesting in contrast with the dirty, oppressive nature of a sewer. It's not supposed to be a real thing that one finds in an average sewer, anyways. Flights of fancy are fun!

And yeah, I wish I could do something about the super bright water, but it's the least obtrusive one I could find- I kinda hate how water (that isn't expensively rendered reflecting water) uses cubemaps to become super bright in the dark. I wanted to give the mushrooms a sense of moisture, though.

Axis billboards = profit.

Can you get a far-away screenshot? It might be wrong, but they just look way to bright to me. I would turn their color down.

I like the first image. Speaks to me the most. There's nothing wrong with the mushrooms, good idea to break up the lighting a little!

I should probably get around to play your newest map. Try adding some vegatation; perhaps some images of plants placed in the same way as the (amnesia) bush. I could give you some moss I made a while ago, could be fitting to a sewer level.

Good luck! :>

Edit:
Sorry for the spam, if you want to I can remove the stuff below.

Spoiler below!

Including two mosses. The above shown is the "watery" kind. The other one is "non-watery". Throwing in a gravestone too lol.

Edit2: I didn't make the textures, so I hope there's nothing scetchy :>

Actually... you don't realize how perfect those are. It just so happens that this story has a quasi-religious theme, so that grave header with 'here lies Acies' is great! I would indeed love to use those. Thank you!
