It looks like you have one end at a steeper angle then the other...this will cause a weird lay as well. Also you should be able to (with some force) bend your RL into a 90* angle. Like demonstrated here
also watch our resident professional instructor Shug and his videos.
Also If your a bigger person the HH may be too small. I prefer the WBBB for just about everything I do...It is plenty large enough for bigger/longer frames. Unlike some hammocks which may have the length but not the width.
Keep trying...it will either work or not...and you can always recoup most of your expenses here on the forum, by selling your gear.
