What is the worst thing that will happen to you if you show her your photos? She might not like them? Then you say, "Tell me what areas I could improve in?" It's a lot of experimentation with settings and sometimes it's all about stumbling upon something incredible. You may go in, though, and she may love them! So have confidence in what you've done so far and please go and show her. I think it's wonderful that you have this opportunity so take advantage of it, no matter how it turns out.

As for your hubby, I'm very sorry he said what he did and hurt your feelings. He may very well be jealous of this opportunity you've been given. Or he may be overreacting at the last minute out of fear of seeing you hurt. Either way, this is an opportunity for you to grow in your talent and you should take advantage of it.

Good luck with it all.
