What you are doing now, it seems, is taking whatever you first come across and running with it, refining, rendering and detailing a (mostly) poorly constructed image. I would take a step back if I were you and look at this on a foundational level, really thinking about form in perspective and how the light hits it.
Not much of a sense of scale is shown in the perspective, which seems unplanned, and as PypeBros pointed out the construction is a bit flat and wonky. For perspective, I would recommend an upshot (looking up) for this one if they are large, at least something that looks less "isometric" for the downshot you have now.
As far as composition goes it still looks a bit squished. The easy way out I think is to increase the vertical space above the pots, with perspective in mind.
The other individual objects are rendered nicely and with a suited palette, but in the image as a whole, it looks like details besides the 2 big pots are competing for attention. The water is rendered as if on a very large scale, with the apparent thinness of it and the way it bends straight down. I would expect some curve at this small scale. (

Instead of making a direct edit I sketched out (very roughly and quickly) several thumbnails messing with perspective, lighting, atmosphere, scale etc. just to give you a few ideas of what can be done, and examples of said lighting used to lead the eye. Later on you can have a busy composition but you have to keep the values in mind.
If you aren't going to change this image drastically or make thumbnails of a piece, try it on another sometime, or in the future if you're going to remake this remake. It makes good practice, for me as well as you. Try many different takes on the same idea. If it looks like you've run out of steam you may have to deviate more from the first few tries. Admittedly it's not ideal for the purposes of pixel art, but, if anything, it makes a good reference for the full-scale image.
Keep on practicing! good luck man!
