Shielded Colony

This is my entry to The Rookies Forbidden Lands contest.
I wanted to depict this colony as a place that is secretive, secluded and full of mystical wonders. The entrance to this colony is suppose to bring a sense of riches, treasure, and mystery; the intention is to capture the attention and lure whoever is near into the magical portal in search for a way inside. The colony is protected by a hazy and toxic green barrier and the only entrance to enter is depicted here. Very little is known about exactly how the magical gate will work, but many have attempted to enter and none have exited to tell their tale.
