It's good, but I would not sell your work just yet :) You, like me, use Blender, which is a rather difficult program to master :) How long have you done this? And Denver, I read your profile and saw that you're 9...... That's the PERFECT age to start blender! Here's an interview I did with a guy in Italy :) http://www.kentstrapper.com/en/italiano-piccoli-makers-crescono-intervista-a-joseph-isaiah-bennet/
Focus on the 4th question and my answer to it :)
PS: I'm 13, and if you like, I could help you learn more about blender so one day you can be the BEST!
Let me know :)
