Focal Length Experimentation - Straight Images

The images below are ones in which I shot outdoors, I stayed in the same position and so did my subject. The only thing that changed was the fact that I varied my focal length ranging from 18-55mm. 

18mm

ISO- 250
Shutter Speed- 1/200
F - 10

24mm

ISO- 250
Shutter Speed- 1/200
F - 10

35mm

ISO- 200
Shutter Speed- 1/200
F - 10

45mm

ISO- 200
Shutter Speed- 1/160
F - 10

55mm

ISO- 200
Shutter Speed- 1/125
F - 10

In these images below the subject stayed in the same position, whereas I moved closer to them whilst also changing the focal length. The focal length I experimented with varied from 18-55mm. I started of with 55mm when I was further away, and as I moved closer I decreased the focal length number down to 18mm.
55mm

ISO- 200
Shutter Speed- 1/125

35mm

ISO- 200
Shutter Speed- 1/160

24mm

Shutter Speed- 1/200

There's no distortion in the initial images I took first, however the second lot of images which ranged from 18-55mm, do look slightly distorted the close I became to the subject. In the last image whereby I'm close to the subject with my lens at 18mm, the nose appears slightly larger than usual- this is an example of distortion.
