Ibis Paint/Medibang: For sketching on my phone.
Paint Tool SAI: For lineart, coloring, backgrounds, and resizing.
Adobe Photoshop CS5: For speech bubbles, texts, and formatting.
Somnote: A very useful app that syncs across my laptop and phone. I use it to jot down writing/comic ideas.
Mouse: Yeah... Because I carelessly misplaced my stylus pen and now I'm stuck using only the curve tool in SAI...
Youtube/Spotify: Background music makes me feel more productive.
Unsplash/Pexels: I use these two sites to get royalty-free images to use as art references.
