I like the closer cropped style here. It seems as if the pictures have a fish-eye lens shot to them but there isn't. It has something to do with the angle of the shots also? And the shots (especially the closer ones) seem to have a brighter center and it gets darker along the edges, like a halo effect.

Any tips to achieve this?
