Systematic Immunity Progress Update: Bosses :-D

So I've been working a lot on level design mainly for the last while. I've now got the the majority of the levels done for the game. That is levels that's I'm happy with ;-) I've also decided to add in boss battles at the end of each organ!
Initially I wasn't going to have any bosses (except at the end of the game) due to workload reasons. But now I think it seems a bit anticlimactic to just play through all the levels in an organ and just move on to the next one without anything special happening. So boss battles it is then!

Here's a quick gif of the progress I've made on the stomach boss so far:
