Thanks.
First off, more tension on ridge and body and a secondary line for guy-out at each pole (three point). Don't be afraid to use a ridge-line if you find suitable tie-outs.
It is also a tad high up off the ground.
Once you get to know your tarp, you'll be able to flat stake it first, then just raise the ridge or poles and have it be tight and pretty close to bang on how you want it to be.
Depending on the time of year/terrain etc, orientation is critical. Knowing winds is more important than in a tent. Finding a semi sheltered area to pitch in makes a world of difference in gnarly weather.
To that end, i highly recommend a bivy bag. A full on stand alone is not necessary, but something like a Ti-Goat Ptarmigan would not only be protection against rain/spindrift, but also with the drafting you will not build up the canopy heat that a full tent will provide. Finding the balance between venting for condensation in colder weather and retaining canopy heat can be a bit of a learning curve.
A properly pitched tarp is a great shelter, and it looks like you have good titanium pegs with it, and are ready roll.
Enjoy the adventure. Once you get it sorted with a tarp you'll probably wanna start playing with sil-nylon tipi's.... :D
