I think it's time for you to at least try to make some arts(even if it's bad).
If you want help,please contact me.
I don't know if you're really into arts,but I am quite sure that you'll do it well.
A tip:
It doesn't have to be sophisticated; just express yourself.
If you're getting 404 Error in your head,just draw HTTP 404 Page Not Found error screen.
I did that too; I was getting total nothing but a big,red ERROR and I just made it and submitted it.
