These are some of the sirens from my videos that I made, plus some bonus art! If you want to use the art, that's why I made this! If you want to see all of my work, check out this studio: https://scratch.mit.edu/studios/33825659/ (Look at past me begging for loves and favorites... I don't do that anymore, right? ...Right?) If you want more of these, I can update this in the future and add more if this project gets enough views and loves, and favorites!
All of these are scaled up so they're easier to use (and to see the detail), so they may not fit well into what you're making. You can edit their colors and their size, but just be careful that some of the parts are made by brush and lines, so those parts may not properly scale! Just change the thickness of the lines to whatever size that fits the scaled version of the siren.
