Nice to meet you.These illustrations have been rejected due to "image quality".
What should I fix them?
By the way, these two have been adopted.
What is the original? Is it designed on the computer or scanned/photographed from a design on paper? If on paper, do you have the original or a printed copy?
Thank you for your immediate comment.
They are scans I drew on papers.
I don't have the original of the first illustration.
I have the original jpeg data.
They were adopted after adjusting the brightness and contrast.It's strange to give myself the right answer, but I hope this experience will help you.Thank you.
Very nice illustrations. 😊
