It isn't ugly at all! (Beauty is in the eye of the beholder.)
BUT>>>>if YOU don't like it, don't use it. It will never make you happy.
I did one with a similar block. I surrounded each block with a zebra stripe then a color stripe ....I'm trying to remember. I no longer have it....hmmmmmmmmmmmm
block

then sashed with a brown that had little stars on it.
It's a WOW quilt that anyone who sees loves.
I think I put another black and white binding on it.
Just remember, if you have to convince yourself you like/love it, don't use it and MOVE ON. Your time and love of quilting is too precious to "have to" anything.
