Invitation Design

I dabble in a lot of things. One of them is basic graphic design.
I've been thinking about including invitation design in our packages. But I need validation.

Tell me, are these good enough?

My Niece's Invitation

This was the invitation I designed for my best friend's wedding.  Sadly, he ignored it, and resorted  to a much simpler design but it's his wedding so yeah, nothing i could do about that.

I never really ask for other people's opinion when it comes to these things but I need them now. Thank you.
