I'm not familiar with this particular style of Impressionism so I may be way off the mark here!
I like bold colour but if used too much, they contradict each other and cause confusion for the eye.
I've put the image into greyscale so you can more easily view the tonal placements across the canvas and ask yourself some questions -
Is a sense of distance from front to back important in this style?
Is identification of elements important?
Are my strongest tones in the right places?
Should the middle distance be less prominent?
I like the sky colours and the way you've painted it - and as this is usually a thread for WIPs I'm assuming this is not yet finished?
I'll be interested to see the next stage - keep going!
