I want to really, really recommend to support Blender Software. I think is a fantastic tool and it´s for FREE. It´s made by artist for artist. If you want to start to learn 3d and get familiar with 3d softwares and tools, this is the answer. I got lots of professional friends that use it as well as part of their freelance pipeline. Give it a go and support it :)
