I kind of like them.
The second one is obviously shot from the metro but I think that the first one is too and, in that case, a tripod would not make much of a difference.
The question I can't keep asking myself is whether or not those are cool accidents or were given some thoughts. Your exposures are pretty good. There is noise but that could be your camera and, in those two shots, it does not bother me that much anyway. The composition is alright. Etc, etc.
But can you take a good straight photo?
