I also did reference collecting, and tried to draw a concept background for the game, but I'm terrible at drawing backgrounds, so here are some of the test textures I did for the UI!
I'm gonna add some of the art I did for the main characters here, The blonde boy here is Joseph Moore, he's the protagonist and a musician, the tan boy is Antonio Cooker, he's the captain of a Whaler ship.
Long story short, I did this undertale drawing around 2017, now it's 2020 and I wanted to re-do it! The difference still shocks me! It's also been so long since I drew anything Undertale related...
