Post some of the things that you wouldn't find in the demo.
Put a couple more builds. Get rid of that picture with the spam roads. Maybe add props (true the majority of the Blockland community doesn't really like them, but they are interesting.)
Post some cool vehicles, like the FROG, Longhorn, and F-18 Hornet.
Getting Killed should have people in a TDM or something.
Include DMs, TDMs, CTF, Siege, and Cops and Robbers.
Show RPGs.
This is a 3.5/10 (2.5 points for music), it's a bad-quality slideshow (again) and barely shows all of Blockland's features.
