I love this! It is amazingly eye-catching and bright, not to mention very cute and girly!
The fact that only four colours have been used doesn't make any difference; in my opinion, it compliments the simplicity of the piece and gives a very nice, bright contrastto the black and white outline and background.These colours work really well together, it was a great choice and looks great!
The pop art theme is definetely there, and is the reason I love this artists work here!
The actual drawing is great and the overall work is very proffessional!
Andy Warhol would be proud!
