Good artistic eye
As many have noticed before, your animation skills are not as great as other's. But, I'm not an animator, so that's not what I'm looking for. You have a good eye for movement and character in your lines. Every once in a while during your flash I noticed a hint of playfulness within the lines. They had some great movement. I do agree that this could have been improved with a higher frame rate. I have two main problems with the animation: one is the downtime when one line would go around in a circle for a bit seemingly without a motive. There was too much of that and it got boring. The second is that there was no culmination. It just seemed to end. I wanted some sort of spectacle or finale to sum up the whole piece, but there was nothing. There was an end credit and then the music just stopped and the whole thing fell apart for me. These are just a few things to think about for next time. I like your aesthetic. Don't stop.
