Cascade: The rating is 10/10, since it's the best symbol here. About being too big, I'll reduce it if it doesn't fit well.
Geno: 7,5/10, I like it, it gives a sence of time, maybe a set based on Celebi?
The score won't get betta 'cause of this last add.
Shinro: Not very good pixelated but very well drawn. 8/10 for all.
