I recieved a very nice print from Matt King. Nice tone, wonderfully sharp. Good perspective correction, so that the supporting piles do not converge to the sky. Quite the spot to fish from.

My son was asking about what the pilings were for. We live inland where there are no tides, so I explained how the deck floated guided by the piles. Looks like the dock is built to accomodate quite a tide and storm surge.

The overmat was very nice. I would recommend you fiddle with the blade depth on your angle cutter, or amount of overcut needed if you are angle cutting freehand thought.
The effect could be from either. The overcut corners tended to pull my eye a bit too much. Mat cutting is a bit of a skill that takes time to build, and you mentioned that cutting your own mats is new to you.
