Hello Divya, I like the channel layout, and I myself am quite partial to more simplified backgrounds/logos. I love the colors used and only really have 2 things I thought I'd mention.
1. The black boxes, what are they for? I'd much rather see the side logos and their backgrounds either continue and replace the black boxes, or have some sort of picture/design there. It seems like it creates a "hole" or a break in the background and sticks out a lot. *Just my opinion!*
2. The grammar of the description. Don't ask me how important this is, I have no idea who actually reads these. It just bothers me to see no periods, some commas, and misuse of words here and there. If you're not a native english speaker I certainly hope you don't take this personally. Here's the version I would use, I hope you find some use for it:
