Harlequin Great Dane icon png download

the image of the dog called "Harlequin Great Dane". I created it in response to the request. It was challenging to me. Because I had not known even the word "gray(or grey) scale". At first,I downloaded the svg format and used the extension of inkscape called "Desaturate" which is <Colour<Filters. but,it didn't work. and then,I downloaded the ping image and made it gray (or grey)with "bitmap trace". I don't know if it would serve as a gray scale. but it was a good experience in any way!
