(Note : This question is being transfered from stackoverflow to gamedev.stackexchange where it belongs)
I really suck at graphics / music / 3D modeling / animation and it's a must-have when you have a hundred hobby game development projects you're working on. I'm looking for different quality sources on the web that provide free resources.
[EDIT] Some resources given by the answers, in bold the biggest resource per section:
MODELS
SPRITES
- OpenGameArt (also contains textures and 3D models)
- LostGarden (a couple of isometric tilesets)
- The Protagonist Domain (2 sprite sets)
- Reiner's Tilesets (also contains a couple of 3D models)
- Flying Yogi (3 sprite sets)
- Has Graphics (a couple of links to tile sets)
ANIMATED SPRITES
