I do believe that FF6 is always a celebrated favorite to aspire towards:

But no one is expecting these grand accomplishments to be imitated now, just considered.
Personally speaking, as someone starting out it's easier to either start with smaller resolutions for detailed work
Or sacrifice the use of details in larger resolutions -- in trade for a more cartoonish style
Take Mother 3 for example:

While M3 (cartoony) and FF6 (serious) are opposite sides of the spectrum, both are acceptable options for inspiration
You use a 32x32 tileset -- so does the game Aquatis over on SphereDev

This style would be a goal that is relatable to your current tile set, as it sacrifices detail for a more cartoony style
You'll notice the mountains in their tileset aren't highlighted or cutout with dark lines
Rather suggested with the contrast from different shades of grey
Their use of snow is a plain white tile
They use spare tiles of light greyish curves to suggest that the plain white is also snow
Sometimes less is more, in other words
