I’m new to wordpress so I’ll begin by testing out the features.
I’ve changed the header picture to one of the standard ones, but I guess I should think about using one of my own photos. My old blog at blogspot had a creative theme to it, but I don’t think I will limit this blog to a theme, but I am sure most posts will be of creative stuff anyway.

You might find the perfect picture among your own photos eventually, but the standard one you chose is a good one with beautiful colours and shapes.
