Wow, this artist. I know some things are hard to draw, but taking a free art piece from Pixabay and using it for your comic? Really?
For anyone who is interested, Pixabay is a site where people post vectors, photos and simple art that can be downloaded and used for free or under certain conditions, depending on the creator. I instantly recognized the pink and purple mountain piece, since I downloaded it from there and used it for my desktop background for some time. Here is the link: https://pixabay.com/vectors/mountains-panorama-forest-mountain-1412683/
The art piece is free for commercial use, thus by law the artist can use it. However, my opinion of them isn't blossoming. Hopefully, the story will be decent.
