A couple of hints is that the top and bottom are smaller pieces and I found doing the white-greyish pieces first a good starting point as they are only in two places, the first block and just off it on the second block to the left of it. Also first and second block on the left have lots of lines. I did about 5-10 pieces a day before I felt I should give it a good go.

Aw man. I haven't even tried this one yet. Good job!
