However, i thought it worth sharing with you some more free resources I found today. This time they are on the official Blender site at https://cloud.blender.org/workshops
Here you will find not only tutorials but actual examples you can work through and learn by experience from! For example, Waking the Forest is the latest artwork by Andy Goralczyk. This inspiring image is available along with 5 hours of commented timelapse, high resolution images and all source files (textures and shaders are packed into the .blend)
It's amazing that these talented artists are willing to give back to the community and share their expertise with the rest of us, all free of charge. If you have learnt the basics of Blender then you will no doubt find these workshops an excellent resource for deepening your knowledge of Blender and flexing your creative muscles.
Let me know in the comments if you find this resource useful.
