I like this shot. Looks like you use a polarizer to darken the sky.

There are several algorithms in use for resizing photos in photo editors. Paint Shop Pro X has "Smart Size", "Bicubic", "Bilinear", "Pixel Resize", and "Weighted Average". I don't know how any of these algorithms work but for me, the "Weighted Average" seems to work the best. I presume PS has similar options.

That sky looks almost navy blue. Artfully composed and cropped.

RE: resizing, if you're a real purist it appears that the many algorithms cited by Cal, are used in various ways depending on the characteristics of the image.

IrfanView (freeware photo editor) uses a Lanczos resampling algorithm as default which is one of the better general purpose ones but there are a lot of fans of BiCubic and some of the others. Each adherent can cite you chapter and verse why their favorite is better than the others.

Here's a thread about resizing that may help you a tad:
