Alletun - Summer Fest (Underwater Lost City)

[Alletun]

Hello

Im trying to make a matte painting of Rapture (from Bioshock).

This is my reference:

This is how to looks like so far. Got the background elements roughly done. If anybody have bright ideas for the Middleground and foreground elements, please share!
Any other input is also much appreciated.

Add some fish or floating debris in the FG - this will help give a good impression of scale/perspective.

coral reef, sunken ship? Yep, totally cheap ideas. :crazy:

or how about an underwater waste dump?

looking forward to seeing more, keep it up!

Can't wait to see where this leads too. Looks like a very great scene is coming
