First Geocache

Well my first attempt at making my own geocache. Pretty standard design, but though I would share and take some critique over it. No tutorial watching on this one, just started grabbing shapes and seeing if I could remember how to do it from what I had previously watched. If you download it let me know how I did, I did already realize my threads werent quite center, but welcome any constructive criticism for it. Thanks
