Ugh, I feel you here. There is a webtoon artist I was in contact with and we sent so many emails discussing the project, paneling, payments, book cover, etc, and she just kept saying she was 'busy' every time I would follow up with her regarding moving further for creating the webtoon episode- like a month out. I figured she just wasn't interested in working with me or my project and didn't have the confidence to tell me this. I wasted some money on her but oh well, I still got some art out of it not that I can really use it.
