I was inspired by their work because it's effective in a number of ways, not only could it be used for multiple purposes, such as; t-shirt design, advertising, branding etc but it also appeals to a broad range of target audiences. The characters are perfectly proportioned, but the excitement lies within them, vibrant colours and a theme of nature (rainbows, valleys) is consistent within each design.
In this range of designs, the emphasis has moved away from nature and is possibly concentrating more on their bodily features, which are suggestive of a robots. Maybe this is the reason for the duller colour scheme?
