That's a good design, but you should know that half of the logo will not be seen because of the FB profile element that will hover in front of it. You have to take that as well in consideration. That's exactly why I've made logo half smaller. Kind regards.
Thank you so much for your feedback. If you approve my design I shall adjust the size of the banner separately for Facebook cover picture, Twitter, YouTube and the Website banner as mentioned in your project brief. Regards
