Regarding the first Kaijuu chart, I think it could be improved in how the notes were used, specifically in the instrumental parts. Often, it's overcharted or undercharted too much in those sections.
As for the second chart, I really liked how it was done. You managed to make the music flows the difficulty it should have for an Expert.
That said, you have a great experience and manages to make the music flow well with the chart, so the first chart isn't a problem at all.
