Alien character design brief: Thumbnail silhouettes.

I was tasked to created 4 alien designs and a creature design for coursework and this is the start of my progress. The first step was to create an interesting shapes through silhouettes then fill out the details later. I split the 4 different races into themes on the different types of animals such as mammals and reptiles and 1 cybernetic/ robot race to give myself a good start on looking for references.

Here are the first batches of thumbnails.
