This is the Adobe Stock Contributor forum, which was created to advise fellow Contributors on questions relating to rejected images, and other issues on using the Adobe Stock platform. This is not the forum to help you with your artistic creation.
Is this an illustration that has been rejected as a commercial asset by Adobe Stock? What reason did they give you? Is this an AI generated illustration?
This is probably not the correct forum for this. I would suggest the Lounge? Should I (or a different forum moderator) move this post to the lounge?
If you want to give this a “modern” shiny look, learn to add reflections. This one currently looks like a drawing coloured in with ink pens.
