I'm not sure

I've had this fabric stashed for years now, just waiting for the right project to come along, so when I spotted the Hammock Quilt in Jane Brocket's The Gentle Art of Quilt-Making, I was totally inspired. So here is my version, ready to piece together....but .....I'm hesitating.  Perhaps, it's because I have followed a pattern in a book and my version is different in that I've used stronger colours and I look at the photo and think am I getting this right?  Do I just trust myself? 

Do you know that quote "Don't let comparison steal your joý."?  Should I just bust it together and not over think it?  Or is that yellow really too strong?
