@aprilshin Thank you so much for taking time to share your wisdom. This was really helpful.
Actually I made the black & white planet small to create depth but it didn't work. Blurring it sounds good. I'll see if I can overlap certain parts of the illustration and will try to make the orange more desaturated. We'll see what works out. I'll post the edited version here.
Also, can you tell me which version should I take forward, is it option 1 or 2?
Thank you so much, I appreciate your help. ️
