'aussehen' and 'aussehend' are both connected to the outward impression of people or things. 'aussehen' is a verb: you use it to say how someone or something looks, for example tired, friendly, or beautiful. 'aussehend' is an adjective and is usually used together with a word like 'gut' (good), 'müde' (tired), or 'krank' (sick), often before a noun.
