...and the question is?

Perhaps your statement that you are "open to any advice and/or criticism" is intended as a question. If so, it would be clearer if phrased as a question.

And, to continue in quasi-Socratic fashion: does it work, as is? Well, output appears to match your description of your intent, so if this is for some production purpose, remember the advice "if it ain't broke, don't fix it. But if you're seeking advice on improvements ... well I'll leave that to those with better fu.

And since you've created a new thread, it would be well to go back to your earlier post and update the top node with a "see also" reference to this thread.
