I don't think it looks to busy, no. But how does it look when it's filled with more content? How does the text look when it's too long for the field. Consider making a worst-case-mockup, not just a best-case.
The icon you are using for the active tab says "map" to me. But I think you mean "near", right? You should consider that people might expect a map when they press it. And fulfilling those expectations is very important to UX.
Are the Stars and feedback related? If so they should maybe be closer together.
The third icon next to the smileys also seems to use an active color. What do i deactivate when I press it?
Generally I get the impression that you have three competing rating systems: feedback, stars, smileys. Plus you can probably reply as well. So yes your UI is not cluttered, but the functions you are visually conveying are confusing a bit.
