I have two suggestions that are somewhat contrary to your question. First, learn to draw. I recommend a book called Drawing on the Right Side of the Brain by Betty Edwards. That and lots of practice. Second, learn to produce and animate pixel art. You'll be surprised by the results you can get with the retro/nostalgia look. Google will find you plenty of tutorials. While not 3d modeling, these approaches have low barriers to entry, and what you learn will help your future efforts artistically.
