Would this amount of Panel/Curtain be too much for the entire rod?

I currently have 5,2M in width, and thought about buying 1 more panel for a total of 6,40M width, to make it more full. However, these curtains already have pre-sewn waves. The 2nd pic is how it looks now, and the 1st is how it would look throughout the entire Window if I would add another panel, which is better?
