Will strength training make me look more proportional?

Stilllosing26

Right know my lower body is much bigger than my upper body. (I am very thin up top/in the arms/chest/stomach area), and very big in the thighs and legs. I just started a strength training regimen and am attempting to gain close to 10 pounds of muscle. Will this make my body more proportional? I want a fuller upper body, and more muscular legs(not necessarily bulky though). I have very good genes from my dad(as he was very big and muscular with an 8 pack and huge biceps, triceps, quads, glutes, and such). I am ready to get started(just wondering if it's worth it).
