Brainstorming and Concept Work

It's been a fairly busy weekend for me due to work so I wasn't able to work on too much sadly. However, I've been looking at various art styles and concepts for our environment to get a general feel of where I want to go with it. It'll be fairly simplistic when it comes down to textures. It'll mostly rely on some ghostly, smoke particle effects that glow to make it really feel like youre in a place that the grim reaper would live in instead of just a normal lake. Implemention of fog, other particle effects, and color are going to be the most important things to be focused on. Here are some images I found looking around that have a similar feel that I was going for.

In order to liven it up just a bit so that it doesn't just feel like so moody, I might go about adding some additional elements such as fireflies floating around to give contrast to the mostly blue world.

I'm looking to create parts of the environment by Thursday.
