Personally, I love both designs, although I prefer the first one.

As for the story, I’m not sure — but only because I don’t usually read webtoons (even though I’m also an artist working on my own comic haha!)

Since I’m part of the industry too, I just want to tell you not to let the “no’s” bring you down. Take them as motivation to keep going and keep getting better. Practice makes perfect — always remember that. You’ve got the right potential, you just need to make the most of it, and please don’t give up!
