Looks great when finished!  
Only improvement I would make is to add washers to the bolts in the base for increased stability.
The planks are not labeled - I did this on my own before assembly.  You'll probably need a step stool to complete due to its height.  Make sure to leave the back side accessible during assembly.
I recommend grouping the parts by height and using a tape measure to make sure you use the correct piece.  I also recommend sorting the nuts and bolts etc. into labeled groups before hand as some are very similar in size.
