My Christian brothers and sisters don’t like this drawing of Satan being killed by the cross. Why?

I write music for a band called “Broken Cloud Machine” and my message is that anyone can repent and be saved because of Jesus Christ. I recently paid an artist to complete this idea of Satan being killed by Christ (the cross) for our album cover / t-shirts. I want my message to be clear…but apparently it’s not. Nobody in faith I show this to appreciates seeing the Devil being destroyed. I’m interested in knowing y’all’s thoughts. FYI the art is intense because we play more aggressive music and im appealing to the hatred of sin/evil. But why do Christians not like this? Thanks 🙏
