pixels header

Hello Skandha, I made a header image (1920 x 835 pixels). On a MacBook Pro 13 inch the header doesn’t occur totally (height is the problem) On a iPad 10 inch the header occurs in height a little better, but not completely. I replaced the original header image by a self made image.https://laura.hagmeijer.nl/sample-page/ You see the result isn’t good. The original flowers are much longer than at the image. Can you please give a solution for this. Kind regards Hans Hagmeijer
