New designs for website

Basically you can create a lot of lines and squiggles etc. and some how the lines will just look creative, and if you have an imagination then you will start to be able to make out an image within the lines, but that determines what kind of imagination you have. Here are some other designs i have created;

Here is a screenshot of one of my designs on a skateboard;
