The sentence is ambiguous because the word "attention" can mean two things, so the sentence can mean either:

1. I present my observations to draw you attention. (A friendly reminder).
أقدم ملاحظاتي للفت انتباهكم

2. I give you my observations, and you are to attend to the matter, i.e., to address the matter. (An order, a demand, or a request to take action, presented in a friendly manner).
أقدم لكم ملاحظاتي، راجياً أن تحظى بعنايتكم

Only by knowing the context can one decide which one is more appropriate.
