Yeah, agreed with skippy and elk bout the pipes, could be bigger or just as big as before, so u get the necessary shading on it. Everything looks really good, the shades you added on the water is what really makes it a lot better imo, although it ends abruptly on the right side bridge, maby add a small shade being cast from the cliffs aswell to get even more depth?. Not a 100% about the character, everything else seems to be drawn in one style except off him. if you can add the "less is more" style to him aswell I think it would be better!
quick edit on the character:

If you still wanna go for ur own char I like it is I suggest you work a bit on the outlines, clean it up a bit, seeing as everything else has quite a dark one. Especially on the arms.
But overall it looks very pleasing to the eye!
good job
Edit:Just noticed it looks like mine got breasts and it appeared to me that this might not be a guy? if it is a man, u should probably consider taking that shade away from over his belt buckle
