My first colored pencil, not the best but its a start.
love the wood rendering as well. i would even carry that back to the barn to weather it a bit and darken (or lighten) the roof to push it away from the fence a bit. i love the idea of using the fence as a frame for the barn. might throw in some brighter yellows and greens to give the tree and grassy areas some punch. really nice first attempt. you're braver than i am and have a lot more patience! keep up the good work!
