Despite being a very weird ship- I don't think anyone wrote a Colin/Luna fic ever, the concept was brilliant! When I read the title, I thought that he goes to save her from someone who captured her! Hehe, but weird is my middle name
You're a brilliant writer, and I loved your characterisations! I just wish that there was some concrit to give, but there isn't and this isn't me being biased

Wow Grace!!!

Colour me impressed. This was an amazing oneshot. I loved it from start to end. The more I read of your writing the more fascinated I get.

Your descriptions and plotting and flow.. all of them are so well done. 

Very nice!  Good characterization on Colin, I think, and though romance is not usually my thing, I do like the unique take on it you've used.  A constructive critisism:

---It had been earlier in the day, and Colin and Luna were walking around the lake together---

That starts out very awkwardly...  To me it would have done better to say "Earlier in the day, Colin and Luna..."  Etc. but again, a small thing. 

Well, it's not that wild or weird, but I did love this fic. It's nice to see Colin with someone other than Ginny in fics and Luna with someone other than Neville or Ron.

Good job!
