My first and only (so far) splice was fly. It looked similar to your's...one side of the crossover tight and one side not quite there. Overall, your's looks better than mine did.

I bounced on it with all my weight and climbed on it a few times and it didn't change at all, but I was never comfortable with it.
I have read that fly is a difficult rope to splice.
