The image was sourced from Unsplash, and is totally attribution free. Such is the nature of that community. If you want to give credit to the original artist I can track that down for you.
My contribution is the stylization of the image in the requested dimensions and thus creating a unique image which you will only find here on STEEMIT. I have complied with the original license requirements, and now re-release this image under (https://creativecommons.org/licenses/by-sa/4.0/legalcode)
The rules are clearly indicated in the post:
To have a valid submission, you need to be the author of the photograph. Sorry.
Totally understandable, and to be honest I'm not here for the competition but rather to contribute to this project. Obviously, I've wasted my time on nuances.
