* For the Draenei Female banner, place that little black strip on the left side on the right instead. It's already fading to black on the right so it wouldn't look out of place.
* To extend the other banner, I'd suggest applying a gradient fill and merging it so that the banner "fades out", then you wouldn't have to tile it.
The second one is a bit trickier to do, if you want I could give you an example.
