Why did he look down on my face after he looked in my eyes while standing close to me? Did he looked at my lips or nose? Did he wanted to kiss me?

So i really like this guy from the garage and we were standing real close to eachother and just talking and after we heared "our" song he looked at me and i looked up at him and he looked in my eyes and then down, i was scared he was looking at my nose but maybe he looked at my lips? If so did he wanted to kiss me at that time? He looked down on my face for a few seconds and then looked away.
