it's really stretched out.Be very honest with me i understand i can't please everyone but i would really like to gather everyone's opinion look at my channel page and let me know what you think. Lol that was my first time ever creating a custom clickable banner!!!
I would wait it out until the 22nd and start creating a banner for the new layout if you will be opting in of course:

I would also do as Bryant said to make sure you dont have stretched images.
22nd!? Omg why!? Why me!?
it's really stretched out.
If you are using photoshop, to avoid messing up the ratio, hold down shift before you drag the corners out. It'll make it look less stretched :]
