What's happening here?

I started this boulder retaining wall last week. What was I thinking with all of the other things to be done in the spring?  Here is my list of things to do in the yard this summer:

• Move the last maple tree away from the row of pines (but where to put it?)
• Remove the badly sunburned dwarf blue subalpine fir and move the one that isn't sunburned to the pond area
• Build a ground level deck near the pond
• Add soil to the north area of the pond, add plants and mulch
• Finish this boulder retaining wall, add steps,  move the weeping crabapple to the corner. Add yellow perennials to contrast with the wine-colored leaves. Move Lanham Beehive pines from front garden to the front of the boulder retaining walls
• Build a small patio off the deck
• Add river rock to the bare ground under the deck to keep the soil from washing down the hill
• Add lattice under the north and east sides of the deck 
• Move remaining plants from the former cutting garden area
• Create a plan for the remaining boulders - where should they be placed?

This is an aggressive list! The most critical thing to get done is the boulder retaining wall, as we would like to add a fence around the pond area and the fence will follow the edge of this retaining wall.
