Gosh! That's what I call art! Looking very good there! If there could be something to give critique out of, I'd say the shadows of the trees could've been a little more deep/dark. But otherwise, very good and detailed job!
oh, like the atmosphere on this! it looks as if a storm is approaching! you did a good job on the clouds and sky. and there seems to be a dynamic in it, from left to the right, as if a strong wind is blowing, blowing the clouds into that direction, bringing a storm. nice and fine combination of the colours, they support the atmoshpere of a coming storm. as Glowydabstrd already wrote, the shadows on the trees could be a bit more defined, deeper, have to agree here. but else, can't see anything else I'd have changed. was wondering if there are no leaves on the ground as the wind seems to be strong and the leaves seem to be so yellow they could fall, but it could be too much maybe. anyway, you did a really nice job on this drawing
