Blackbeard and Usopp related in some way???

Hello im quite new to OP just caught up with the anime , but i just noticed the similerities of Blackbeard and usopp. The similerities that i saw are: 1) His nose 2) His eyes 3) His lips 4) His hair. I think they look too similar for this to be a coincidence, im i the only one to notice :0 p.s: This is my first ever post on this subreddit so dont be too harsh :D sorry for my bad english
