Are you sure that you doing a wood texture , looks more like a brick wall to me or if its wood those planks are floating on top of each other
Also most of your seams make straight line [seam on the top and on the bottom ] this is not how you build something durable you want to offset them as much as possible for stability + if taken only from visual stand point you are creating center monotone point of attention that wont tile very well , so maybe shift them around add more randomization , to get rig of the floating effect add something in between like mud or moss or use overlap
