I expected a far less lower rating, so I'm not going to complain. Although, the poem isn't supposed to have a rhythm, each line is it's own in itself (does that make sense?). What I mean is, each line should be read without an expected rhythm. But if the reader assumes there is a rhythm, then it's completly my fault.
Well, it's not entirely your fault. It's just that usually, rhyming poems also have some sort of regular meter to them.
Otherwise, you could also be writing a freeform poem, which is more prosaic and has fewer restrictions.
