Answer:
The first comma can be omitted, and there should be one after timid.
Explanation:
The correct sentence would be: "From my perch on our front porch I felt a timid, gentle breeze stir my long, brown hair". The firs comma isn't needed because there's no need to separate with a comma the subject from the verb or action. However, there's need to add a comma between timid and gentle, because it's an enumeration of adjectives and they need separation from the noun (in this case, the breeze).
