Watch your focal lengths when taking pics. These can make or break an image. For each subject you have to find a good length to compliment the subjects features.
This is 18mm
This is 24
These are crap, the smaller the focal length number the longer it makes a face. These pics make me look like i have a long nose that almost comes out of your screen.
This is getting closer but i still think its not good for my face. This is in 35mm
This is around 50 mm and if it wasn't for it being shaky i would think it would be the best of the pics showing how to do a good portrait for me.
This last one is between 85-135mm i didn't get the length. As you go higher up the numbers the flatter the object looks. The last pic still give a good feel of the shape.
