You're being too hard on yourself and all the work you've done. Whatever imperfections there may be only add character to the quilt (and IMHO, I have a hard time seeing them).
I like the colours - they're soft and their transitions give the quilt a flowing movement.
It's very true what Katier825 said - Bali Pops (as well as other brand pre-cuts) are NOT - I repeat NOT always cut accurately.
I found this out the hard way also, with my last two uses of Jelly Rolls.
Which leads me think I may abandon future purchases in my effort to save cutting time.
When in actuality, it adds more time to the piecing process by having to make up for the supplier's inaccuracy.
But to say again, I think your quilt is great! :lol: :thumbup: :lol: :thumbup: :lol: :thumbup:
