first shot:downwards and slightly to the right (like 5.30) very soft airm to land bottome of dirt patch
second shot: angled at about 1-2 o'clock soft-medium getting 2 cystals and land above the far side vertical patch
third shot: down the vertical patch till you are around the bottom
fouth shot: to the left about 7-8 o'clock so that you hit the arrows
I still have to finish the level using above I think you need a lot of luck
