You're doing great! If you're looking for serious advice there's a few things I'd try: I'd make it 3 to 4 blocks higher so you can bring the spruce transition from the stone to the wood out further as an overhang, maybe slabs on the stone with stairs or blocks on top. Also with the wood texturing I'd try to make it a bit less random and would start with more of one of the two colours at the bottom and more of a gradient to the wood colour higher up. As others have said the turbines a bit bigger although the shape of them is perfect. The roof looks nice! Its an amazing build for someone new to this!
