Drawing for illustration

Hi
i need drawing illustration of design of locks which i want to make, door knob lock and deadbolt lock( examples attached )

the locks design will be inspired by the smiley face on front and back of door knob and on front of the deadbolt , all the designs smiley nose will be the location of the cylinder (where you put the key in )
i attached also one example of the back only of a smiley door knob so it will give you an idea.

i need 5 different design of fun looking smiley face locks at the spirit of the smiley lock i attached here.
**back and front drawing of door knob , only front drawing of deadbolt
**5 different smily faces (happy and\or fun ones(: )

please have experience with drawing and ask me any question you need to know about the project

thanks

daniel
