Hi @pipoune, that is stunning portrait, it is a great idea to do white on black. I thought about that too. I like you love to details and precision. Real beauty. Of course the portrait of John Lennon is also perfectly done. By the way, I noticed you used #ntopaz tag but it is not enough in order to be seen by #ntopaz curators, you should post via their app. I am attaching a post of one of coordinator, when you have time try to read through. When you post there, you can't post many pictures but important the main one and some text. Once you posted, you can edit in Steemit and upload those that you wanted to include. Wish you good luck!
