Hmmm...

While the vertical format is great for smartphone screens, I also wanted to use negative space to create a distinct mood.

I believe that negative space can express a character's inner emotions. In this piece, the character is small, and the background takes up about 80% of the canvas. By drawing the character so small, I can evoke a sense of loneliness and solitude.

Another key point is the placement of the cloud shadows. I intentionally kept Caine out of the shadow. You can see the boundary between the light and the cloud shadow. I used this high contrast to make the character stand out and emphasize their presence.

Finally, let us look at Caine's angle. I purposely hid Caine's face and positioned them to show their back. If their expression were visible, this artwork would probably feel cute rather than lonely. I enjoy drawing figures from angles where you cannot see their faces. This approach leaves room for viewers to wonder what the character is thinking.
