Okay....
So the jist of this Flash is, Pikachu says no to the trainer, so it gets kicked.
That's it. That's all there is.
Considering how Pokemon has been done to death, this is all you could come up with? Well, whatever. Here's my critique.
There was little to no animation in this video, but from what I saw you need more work. It just looks like a bunch of key frames smashed together when the trainer is speaking(also Pikachu). Then you move the trainers symbol a little while you had an irrelevant song playing(After "Whatcha Say" the rest has nothing to do with the Flash). Not even sure what you did to make Pikachu move but it looks odd. Still, despite this since you at least attempted you get a half star for that.
The other half star is for your art. It's not the best but you have a style I can differentiate. Not sure if that was on purpose or not. I was disappointed at the end when you decided to be lazy and scribble the third and last scene of your Flash. It would have been forgivable if you put effort into it, but you didn't.
Someone said this had potential, and I agree. However, you just decided to be lazy and not take your time with it, as indicated from the last scene. I suggest making more of an effort on the actual content of your movies and of course the art. Don't half ass it. You start out with a certain quality keep that quality going until the end.
Oh, the other star was for the loader. At least it doesn't loop, can't tell you how annoying it is.
I know you can do better, I look forward to your next video.
