good lighting and focus because the lighting was hitting the subject at an angle where it made the colors pop and look nice

good lighting and focus the necklace is focused in the way i wanted it to so it could look more interesting and the lighting is hitting good

this photo is leading lines because you can see the lines and way its built in the instrument

rule of thirds the ornament is put on the side and not in the middle

simplicity because theres a main focus with no space and you can tell the whole picture is about the skeleton 

Multiple subjects there are many crayons that you can look at.
