awww, this looks adorable!!!
The thing with black card background is that it looks very sexy BUT, at night should be in a well lit place as then the butterflies aren't really that visible. But I think since your punches are a little bigger than mine were so it'll be alright. What punch did you use?
The punch is a lot bigger I think. I'm not sure what brand it is, I will ask my mum as I borrowed it from her.
I have a few different coloured card backgrounds to try now, I can see this being very addictive!
