A short film on a low budget usually has faults in camera work, sound quality, and continuity. This one on the other hand excels. For that reason alone I rate it high, even though the storyline is predictable and borders on a river of sentimentality. (In this case the river Arno.) The writer surely studied classic drama, however, to achieve such a fine balance of unities in sharp detail from beginning to end.
The closeups deserve an extra measure of appreciation from a technical standpoint. Juxtaposing colorful images of renaissance painting with comparably vivid live drama must have required many hours of exacting editing. Good job.
