I think it looks neat! Like a light illustration out of a fairytale book that doesn't end too well. I think the outlines closer to the foreground can be edited to be a darker grey so depth is better perceived. The background trees can either use a slightly darker grey coloring (compared to the color of the water) or have lighter outline sketches of trees to make it feel more dense. The pencil sketchings of the person's clothing could fit the form of the clothing more (or just sketched in one direction if lazy). You should experiment more with this style
