FireAlpaca 1.0.29

FireAlpaca is a free image editing and drawing tool that can hold its own against premium packages. It includes the essentials, such as layers, multiple image capability, and flexible tools, and is nicely organized. It's not a match for Photoshop but doesn't really try to be, nor is it optimized for digital snapshots. It's well suited for freehand drawing, though, especially with a digital pen, thanks to some interesting features.
FireAlpaca's Snap feature creates a variety of perspective overlays: Parallel, Crisscross, Vanishing Point, and Radial. You can drag these overlays around the image, zoom in and out, and make other changes. They're great for creating comics, anime, and illustrations. FireAlpaca lets you draw and color your own image elements, paste in and modify other images in multiple layers, and do many of the things you usually need a pricey premium tool to handle.
