This is an awesome post ! Generally I prefer classical art to modern. But I love the second painting you posted, it tells me a story.
The big problem with art is that it's highly subjective, but the art world is full of snobbery. If you were a well-known artist with a big name, your paintings would sell for millions, but if those paintings were presented anonymously or from an unknown artist, no-one wants them. But sometimes there are ways. There was an exhibition in London a year or two back (sadly I haven't been able to re-find the video) full of art by non-artists, but by marketing it cleverly they got great attendance and sold a lot of paintings for decent prices.
Perhaps your art should have extended to destroying them in front of the people who refused to buy. "I made this just for you, now I burn it on video just for you".
Honestly, I prefer classical art as well, but it is impossible to gain enough experience, talent and skill to do it. At least for someone like me.
But I realized that I could make pieces like this and I tried to enjoy it. And I did.
But the fact that people didn't value it at all, or at least the people I was trying to sell to didn't value it, had a devastating effect on me. 😞😞
It would have been a very different way to put it on social media and get attention, to make these videos and then there might even be people lining up for these paintings ahahahah people really like things made by people who are heard and known. 😁😁
Marketing is extremely important🙏🙏
