People are SO harsh!
The low frame rate and less than orchestral production values on the music are easily forgiven.
You're one person, you had a vision and you made it come true. The mech transformation scene was particularly well realized, very smooth! I love the cute cat character designs. I thought it was clever to use so many stills but then vividly animate what you want your audience to be focusing on like the swaying foreman. I would love to see more of your work!
