Is my 70 year old dad onto something with his newest hobby?

My dad recently started painting and testing different techniques, etc (of which I'm not knowledgeable enough to detail). He's always had great drawing technique but is new to the world of paint.

This is his latest work that I think is pretty spectacular and think he should find a way to get his work seen outside of just his basement.

Am I just being a supportive son or does he really have a talent here that he should try pursuing a bit further than just being a "basement hobby"?

I'm happy to post more of his previous work as well, if desired.
