The proposition "two people have two varying opinions about whether or not a piece of artwork is beautiful" is an objective one.
The proposition "that artwork is beautiful" is a subjective one.
In general, objective propositions propose something about an objectively existing world that they (usually implicitly, not explicitly) propose to exist and to be the potential cause of an indefinitely large number of possible sensations. Subjective propositions say something about the state of mind of a single subject. The means of verification or falsification of objective propositions are proposed to be publicly available. The means to verify or falsify subjective propositions are not.
Saying something is ugly is a statement of objective displeasure towards something whereas saying something is beautiful is a statement of objective attachment towards something - in this example a piece of artwork.
You could say that if you like. Or, conversely, you could take the route taken by the poster called RJG and assert the opposite, that all propositions based on experience are subjective and that the only objective propositions are those that are logically certain (usually known as tautologies). Either way, in my view, you lose a valuable distinction that I described above.
Saying something is ugly/beautiful is saying something about the unique, singular relationship between your mind and that thing. I think it's useful to class that as a subjective proposition.
