Drawing face using computer components

This is my first assignment of photoshop which required to make a face using computer components.
For the face the computer components used are :-

1)Webcam - as Eyes and its base as Eyebrows
2)Handscanner - as Nose
3)Printer - as Mouth

IN order to make this face i used a layer of shapes from the shape tool - The ellipse tool . once it was done then using the gradient i just marked the above part of face ie the forehead and just brough it till the level of hair which formed as the head. then using the smudge tool i crossed over it to make it appear as hair.
After it i made another layer which made over the layer before and filled it with yellow colour. using the opacity i adjusted the colour in order to bring the colour of the head and hair which i did in the first step.

after this i used the computer components . i opened the image and using magic wand i selcted the picture . then i pressed ctrl+shift+i and I selected the inner part and copied to the face. The same thing i did for the nose and mouth. Later i adjusted them by rotating and adjusting them to proper place in the face.
To add additional things i just coloured the cheeks using the spray tool and then by using the smudge tool i just scattered the pink colour a bit to be even.
