New to Physique / Bodybuilding - any advice based on these pictures?

[CanuckFit22]

Hi all, I'm quite new to the world of physique / body-building. I was hoping some experienced people could critically look at these pictures and let me know what areas of my body are under-developed and I should work on (and any advice on how to do that would be amazing). I don't know anyone seriously into this so don't know who to ask for help.

Thanks so much
