would this be a good first sentence?

That's three sentences.

No. Nor would it be a good last sentence.

Is this for a creative writing project?

Here are some ideas (I write, too). Opening sentences usually have more impact if they are shorter. This doesn't mean you can't have a memorable longer opening sentence (read Jane Austen's opening line in Pride and Prejudice for an example of a classic and fairly long opening line: “It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.”). But you're not Jane Austen. Consider just going with the last two sentences or even the last sentence in the little opening paragraph you posted.
