Perhaps, but it is not completely random. It is composed of the first letters from the words making up a phrase (which by the way is not from a poem/prose or any existing writing; entirely my own), some upper & some lowercase, prefixed and suffixed with a sequence of numbers and symbols. So it has much more order than a random sequence of 46 symbols, but unless you keylog/phish me or something like that, I don't believe it can be brute-forced anytime soon, which is why I went for a (over?)long, unique phrase. KeePass reports it as having 222 bits entropy although I don't know how accurate an analysis that is.
