Photoshop: Background change & blemish

BEFORE

AFTER

 It was definitely helpful to know how to blemish. Now I could change my pictures if I don't like a blemish on it. But still... I don't think I'll use it much because people should be proud of how they look like and shouldn't change it on pictures. But yes, it was interesting.

I like that it looks real, There could really be a building in front of a mountain. Sometimes it was hard to get clear borders/lines because my tool I used just did whatever it wanted. I didn't like that.
