#3 and #4 are fine.
i'm going to beg to differ here and say that it is not a horrible shot, nor is it without merit. however, it does fall into the category of a shot which works better as a part of series, perhaps of the same lamp from different angles. there is effort and thought in composition here, but it cannot hold water as a standalone shot, because it is simply.. not interesting enough.
something with more character, perhaps a play of light and shadow, for instance.. would be better suited as a standalone shot here.
that said, choice of WB and exposure seems ok to me. keep shooting.
