Sadly, haters are gonna hate.

Great find and I love your interpretation of the photograph - you truly made it into your own and that is what art is all about! I went to Art School and alot of the pre-work was looking at other artists, as many as possible and try out things, even outright copy them - that's how you learn to experiment and find new and interesting things and slowly something original will come to you.

Picasso looked at African artefacts and other religious objects and statues from tribes - and alot of other modernists did aswell withouth giving it the proper credit.

Thank you for sharing your art, keep at it bro - you are talented.

No it's not, it is still an original artwork, OP just used a reference picture to paint it, (hardly like a colouring book is it?) and frankly, so what? - it's still a good painting!

People need to chill and lower their pitchforks
