@udaya_sri There's no rule of when you "have" to change your profile pic - whatever you feel best reflects you and how you want to portray yourself to the world! Personally, I think as long as it's *close enough* and doesn't look like someone else entirely, then you're fine.
Going on 3 years old after the end of 2024 - aside from a new hairstyle, it still holds up accurately today! It's also the same profile pic I use here on ProductHunt!
