Hi! :) I released some free tiled RPG graphics assets here, which I've been drawing over the past 2 years for my game project.

The quality and style varies, some of it was made pretty quickly and might get improved later on, but I think you might find at least some of it useful. Generally I aim for a realistic and a bit vibrant style. There are 103 tiles, 64x64 px in size, which represent different terrain/surfaces and blend with their own type by the edges. Additionally there are 322 objects, which can be the size of one or multiple tiles. These represent trees, buildings, stones, ores, chests etc. and have transparent background, so they can be rendered on top of the tiles.

Here are some illustrations of the tilesets in use:

And finally a preview of the tiles and objects below (note the larger objects are scaled down in the preview):
