"Although" and "but" aren't both needed, you should use one or the other, not both. "It's" is a contraction for "it is". After that you need something that pairs with "is". "nice-looking" is an adjective equivalent here (this isn't a universal pattern, nice-looking is just one of the adjectives like that). Alternatively, you can replace "it's" with "it" to get rid of the "is". "look/looks" conjugates differently depending on who uses it. You use "look" with "I", "you", "they" or a named group of people, but "looks" with "he", "she" or "it", or a named individual
