Weekend photos

Took some pictures today, didn't know how to actually Photoshop them so this is how it turned out with a little amateur photoshopping done.

Does anyone have any ideas on how you can make these photos "pop" a little, or make stand out more?

Ideas are alway welcome! :)

Autumn day

I'm new at this photoshop thing, but here is one picture - but different BW backgrounds.

Which one is better?

Hope you'll enjoy this site, I'll be posting some pictures, trying to keep it simple and regularly.
