I agree it makes sense to specify that it is not certain, by adding "it looks like" (or "it seems like", or other wording that would not be too long; as another comment mentions, "looks" can sometimes be wrong). The other stuff might be unnecessary, although it might depend if it is implied or expected according to the context (in many contexts I would expect it to be unnecessary; another comment mentions how it can even be wrong sometimes).

(Your message is better than the one with a lot of noise, though.)
