My brother and I started working on a map a few weeks ago we're calling Bad Science. The theme is an underground cave system juxtaposed with classic villain science. We've both been casually mapping for and playing CS for years but never really had the support to truly test our work. I have a degree in Game Art and plan to create as many of own assets as possible.
You can find my steam profile here, and my brothers (Roger_That) here, as well as the link to the map here. If you have some time check it out; we're always open to feedback, especially from more experienced mappers!
