Design

I personally use the products and services below and recommend them wholeheartedly.

Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. Advanced users employ Blender’s API for Python scripting to customize the application and write specialized tools; often these are included in Blender’s future releases. Blender is well suited to individuals and small studios who benefit from its unified pipeline and responsive development process.

darktable is an open source photography workflow application and raw developer. A virtual lighttable and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them.

DragonBones is an open source project for 2D skeletal animation. It has a skeletal animation design panel named "DragonBonesDesignPanel" and a 2D skeletal animation library based on ActionScript.

Krita is a free-software and an open-source raster graphics editor, designed primarily for digital painting and animation purposes.

Sketch is a digital design app from Mac. You can use it for UI, mobile, web and even icon design. If you've been using Photoshop for these things, then you should know that Sketch is a very capable replacement.

Tiled is a 2D level editor that helps you develop the content of your game. Its primary feature is to edit tile maps of various forms, but it also supports free image placement as well as powerful ways to annotate your level with extra information used by the game. Tiled focuses on general flexibility while trying to stay intuitive.
