Overall it was meh
I guess my biggest complaint is the fact that when you have 90% of the movie obscure the face of the hero, and don't seem to really use his signature hair color or make it look like him at all, it tends to detract from the fact that this was supposed to be a Pico Flash.
This felt as though it was a standalone kind of cartoon would have been great without anything involving the site, but it really seemed that beyond the title felt like far more of a stretch to consider it remotely related to Pico really.
On an artistic aspect, I really enjoyed the soft use of shadows on the floating objects, as that looked really nice, and look forward to seeing some more from you sooner rather than later.
