Very nice remake of someone else's art ~ You cited yourself 4 times but didn't cite the original artist and you've created a direct duplicate. Even if the artist had given up all creative rights to their work it would still be in good taste to credit them for their work (the concept, the lighting, etc) even though you have re-created it. More-so because it is a direct duplicate. Seeing as you are advertising this work as solely yours, over various streams of media, please consider offering the artist a citation, perhaps with a link so others artists can be as inspired by them as you are.
Hello, I have featured this piece in a recent feature. I wanted to also thank you for sharing this on deviantART. Your artwork is one of the pieces that really impacted me this last year. Thank you for sharing and making this an amazing place. Best wishes,
