Wow good work
Some feedback:
First Image :-
When changing the size of an image, in this case the social logo, make sue you keep the aspect ratio. The width is stretched because of failure to do so.
"The channel of" text looks kind old fashioned, no offence
, try not to emboss or if you do make it only slightly visible. Other than that it looks great! Love the design!
Second Image :-
I personally feel the text is to big. It just looks squashed into the banner. I'm personally not to keen on the color choice. Try using
Adobe Kuler. It's a great site to get colors that look good together
Same thing with the aspect ratio.
My personal favorite out of the two is the first one
Good Job. Hope my feedback helps.
