How can I improve my frame past 18 and am I a framecell? (with photo)

[Greycell223]

I'm 18 and 6'3 but I feel like my frame is lacking a bit.
I started training 3 weeks ago focusing on my delts but I also want to improve my actual clavicular bone lenght.
I heard the clavicle can still grow until 25 but its quite minimal so I was wondering what were the best things I could do to improve the width without any growth factor injections.
