Team Twist - Creature Design

Recently I was asked to produce two creatures that could be used in our first level. We decided to go with the sewers, so we needed some dudes that would fit the setting. We've decided that we want to use Greek mythology creatures, but completely redesign them into our own.
Here I've produced two creatures with couple of variations.

There isn't much to talk about this creature other than we wanted it to be quite big.

In Greek mythology Charybdis is described as a whirlpool that sucks up all the ships that come by. At first I drew a big mouth  sticking out of water, but then me and my team decided to redesign the creature, so I drew two different variations and then a couple more on the chosen design. We also decided that player will not see any of the body, simply because it will save us both time and processing power.
