404 Landing Page

Hello everyone!
Today I started working on this 404 Landing Page and my current process is acceptable in my opinion.
The upper right should be the navigation if you're asking yourself what this should be, though this minimalistic style is something different.

You can find the used illustrations here:

I can't make them by myself (never tried to make illustrations) so I've used this one. :D

Fun fact: 404 theres nothing here is a rhyme in german

Hope you like it!
Have a great day!
