Work in Progress - Sketch drop

I was avoiding posting sketches, unfinished work and processes on my blog, but then I remember the purpose of having a blog like this is to streamline the information about my personal art development history.
There are many places online where I can post finished artwork, and the need to expose these sketches to the world is still vital, so this is the place, my home to sketch, work in progress and others as well as finished art.

The following works are unfinished and done fast, I will hope to render them later in full color and detail.

A) Criminal scene in bathroom:

B) My hometown in a dystopia spin:

C) Environment thumbnail practice:
