A Sheffield street artist has defended his giant mural of snooker player Ronnie O'Sullivan saying that the project is "unfinished".

Chris Ashmore was commissioned to produce the artwork featuring seven-time world champion O'Sullivan for the back wall of the Spot On Snooker Club on Langsett Road.

Some residents said they liked the mural while others described it as "zombie-like", "shocking" and O'Sullivan's face as "skeletal".
