Fylo landing page with two column layout master

This is my first landing page project ever.

I have trouble with the illustrations and menu while the screen changing its size, please for help there. Thank you.

P.S. For the people which don't know, you can change the color of every .svg file, just Open with... Notepad, and search for all "fill" with HEX's value, then just change that HEX value in the HEX value of the color you need.
