Music doesn't get old, friend, and neither does the appreciation for a received gift. I still like it, still am just as grateful for it and still have a few local copies of it (as it hasn't been available on youtube for a while now). That being said, you have no obligation to make a new one for me. I would hate to waste your time.
I have no doubts that you improved. And you know me, I'll always appreciate anything given to me, as I'm certain Marek does. It's entirely up to you though. Also I now wonder, do you still upload your pieces anywhere? Your youtube channel is very silent and I don't remember anymore whether you've had an alternative. Not gonna lie, I've had a lot on my mind these past few years. Lastly, Marek is not available anywhere except discord, so if you wanted to contact him personally, be sure to send me a note so I can give you his ID.
