I love those antlers. And what a cute face this guy has!
Also, I always post all my own deer art in Fan art Because it's fan art of the endless forest. And I personally don't think art like this belongs below a cut. Very nice job!

When you create a new blog, or edit an old one, you can see, on the right, it says "Split summary at cursor." If you press this, you will see the blog split in two boxes. One top, one bottom. If you type stuff at the bottom, it will be "under the cut". This simply means that, if we stroll through the picture categories on the left, like "Fan art" or "concept", that we don't see your picture immediatly. We have to click on the title first, before we see it. If you put it under a cut, that is.
This is often done with pictures that have blood or perhaps nudity in them. To not confront people with something they'd rather not see. With any ordinary art, I wouldn't worry about it. Maybe if you have a lot of pictures! Then it could be nice to put most of them "under the cut" Hope that helps!

I guess you could go posting on countless pictures then. This one doesn't seem bigger than usual to me, Moonsoverwater
