Don’t know if it’s too late, but some things I’d recommend are: 1) most of the image seems to have a moody, ambient light, however the pale green foliage in the foreground and the yellow on the trunk makes it look like there might be some direct lighting. Also, the background light seems to be a mint green/pale yellow, so I can see where you got the yellow and blue highlights, but it feels slightly at odds to break up the lighting like that just in the foreground. 2) The short, choppy strokes look more like fur than bark…I might make at least some of them longer? Love the gnarled character of the tree in the foreground and the mood in the background though!!
