The power layout (looking at the image on the site you linked to) seems poor. Obviously it's constrained by being 2-layer and narrow, but the track running under the chip to connect the boot button is inexcusable - cutting off the ground to the decouplers on the left hand side, when there's plenty of space to take it up the edge close to the row of DIL pins. Also R87 (boot switch resistor) is in the wrong place - should be close up to the flash chips such that the long wire leading to the boot switch doesn't load/put reflections on the timing-critical flash nCS. C101/102/109 all sharing a (distant) GND via isn't ideal either.
I dare say it'll work, but if it's intended as a board suitable for overclocking it's unfortunate to have these limitations.
