A list of what I've uploaded should be there, most of it is actually free to download (I'm doing a mixture of free and paid assets). I've been able to master some of the Blender shortcuts to make sure the parts of each object connect together to make a wide variety of assets. It's quite rewarding seeing the completed object come from the imagination.
