I lost my dad too, in 2018. If making things that would make him proud of you helps you move forward that's really great. It's a huge step. But then, maybe later, you might switch this mindset to a new one which will be: I'm going to do whatever makes ME (not my dad) proud of MYSELF, because my life can end at any moment (maybe next month, maybe next year) just like my dad's. And that's when you will find true happiness back in your life. Just make yourself happy. That is what he would love to see most. I think. Wish you the best in this journey and congratulations for moving forward.
