Steve Prescott is an illustrator for games, calling himself an “illustrator of fantastical things”.
Prescott does many concept drawings of weird and obscure creatures and characters, mostly using pencil, colouring pencils and brush pens. His drawings are often very cartoony and stylised.
The majority of his work is quite normal, like 99% of most other concept artists. However more recently he has been doing more unusual, kind of creepy stylised art work which I actually like a lot more, for example his fantasy monster pasted on top of what was a starbucks cup above.
Prescott will work well with the idea of using Kerby Rosanes’ way of art production, it could add to the unusual fantasy feel. However I don’t see how it would fit into any of themes on it’s own.
