Need some music advice!

[Baronshy 25]

Hello. I'm a bit new to the forums but I hope to become good friends with everyone I meet here. Anyways I've started writing my own piano scores and one of my favorite parts of music is arpeggios because of how a song can be composed entirely of arpeggios. But there is a problem. I suck at swapping to different arpeggios in my writing. I can't seem to make arpeggio swaps the way masters do. Like when I try to change from a D# arpeggio to a C#m arpeggio it doesn't sound the way it should or the way I want it too.

 

Any advice or help with this area of music would be very helpful as I'm trying to write some stuff for PMVs, which will have an electronica sound to it. Who knows? Maybe I'll make DJ Pon-3 look better.
