Recede - means showing as more distant - with cooler colors , softer edges..
You have a lot of pointed areas in the land/water.. try to avoid repeated shapes or spacing..
The sky is a nice vivid blue, suggesting a sunny day.. but the land seems a bit dull & neutral with no shadows or highlights..
The water could be matched a bit closer to sky blue color.. like a mirror..
You can paint the sky & the water areas at the same time with same color , then do the land areas & hills overlapping.
Your trees look nice..
The far trees could be a bit cooler/ blued a bit to add distance effect..
