Traps Look Small from Front but Big from the Back

[igregie]

Been trying to fulfill my desired physique, and so far it is going well.
Although, I have a question about my trapezius muscles.
It seems that my traps look small from the front compared to how big it looks from the back.
Maybe it's just me and my perception(s), but does it have to do with "muscle attachments" and my body structure.
For example, could my collarbones be affecting it?

I'm not really worried, just curious...

EDIT: My collarbones seem to be relatively high and slant slightly towards my neck.

Most probably relative lack of mass on upper traps compared to the middle and lower traps.

Target your upper traps more through heavy shrugs and deadlifts.
