Take a look at the photograph of Amy Winehouse below. Now take an even closer look, with the knowledge that this isn't actually a photograph at all. It's a pencil drawing.

Artist Kelvin Okafor specialises in creating stunningly realistic drawings that are so accurate they are often mistaken for photographs. He is rapidly making a name for himself in the art world, having had more than 50 commissions and exhibiting his work at galleries across the country.

The Middlesex University Fine Art graduate takes between 80 and 100 hours to complete his amazing pencil drawings over approximately three weeks in the studio. His works command prices between £5,000 and £10,000, depending on their size.

The Tottenham based artist said: "I've always been creative, but fell in love with using pencils in particular. It was only when my images started to create a buzz with other Middlesex University students that I realised their impact.

"The attention I’m receiving is surreal and hasn’t really sunk in yet. I’m usually sheltered from it in my studio as I continue to build my portfolio, but I’m really humbled and honoured that so many people appreciate my work. I hope to have my own gallery in the future."
