The simplest and most common way of sharing self-created art is to upload it to your EC gallery, which are the photos that people (depending on your privacy settings) may see when they click on your profile. To upload photos, go to "My Settings", then go to the "Pictures & Albums" tab. You can create albums and add photos from there. Please note that all photos uploaded to your EC gallery will go through a moderation queue for approval before they become public. This usually takes like 10 minutes tops. You could create a "Blog", but like I said the most common and easiest way to share your art is via your EC gallery.
