In fact I am not ignoring advice, but simply do not know how to implement it all as I am still learning. No need to be unfriendly.
If you don't understand advice given, why you don't simple ask?
If you ask the right questions you will get the right answers.
If you don't ask, it's easy to think that you just ignore good advice.
Turning up the contrast between colors won't help if you don't seperate planes clearly.
The overall contrast is really low. It's stillv really low, although you turned it up.
Maybe it's because the darkest colors (at least of the lantern) are really bright, but that also could just be my impression, since I love dark shadow tones and I just looked at the lantern.
the contrast between planes of different direction is not really there in all objects, at some yes, at some not. That can be fixed by using different colors for top planes and front planes - same principle as with the dock poles.
Consider how i upped the overall contrast and the front and top plane seperation.

If you look at your lying barrels you can see that they are just flipped and that the lightsource don't changed.
Also the light on the metal rims comes from the other direction.
there is no consistency of lighting.
The same issue might appear in other graphics you will make/made.
