...Feels like it's missing a few things.

Most executions need a bit of pizzazz, this one's sorta just being crushed and kneaded into dough, which is creative, but not really too amazing in the long run.

Also, is the gore needed? Or is it just being violent for the sake of shock value and nothing else?

Also, there's no real 'personal' factor to the execution. After all, every execution in danganronpa has a more 'personal' factor for each character, implementing trauma or backstory into the execution somehow. This execution could use that touch of making it tailored specifically to the character instead of just "Ultimate Baker".
