RE: Losing his eyesight gradually due to a rare disease, an introverted painter hurries to finish his last painting to participate in an important exhibition going trough an existential crisis.
This is a really nice premise.
So we get the stakes, could you make the exhibition something specific? Like a major biennale for example.
The only other note I’ll make is that it’s not cinematic. Nice premise but ultimately, some guy painting doesn’t make for good cinema. Could you inject a conflict? Perhaps he has to reconcile with his estranged son, daughter, or wife. What if the estranged loved one is the only person he knows/trusts to be his hands and help him finish the painting?
