I used a 16x16 sprite pack to make a 640x640 map in pygame:

The problem is that everything is extremely tiny. How could I go about making the expected "JRPG" look, like this for instance:

I have tried so far to double the size of the map tiles using pygame.transform.scale(tile,(32,32)) but that makes everything look terrible:

Here is how I am rendering the map:

import pygame
import pytmx
from pytmx.util_pygame import *

class tileRender:
    def __init__(self,filename):
        tm = pytmx.load_pygame(filename)
        self.width = tm.width * tm.tilewidth 
        self.height = tm.height * tm.tileheight
        self.tmxdata = tm

    def render(self,surface):
        ti = self.tmxdata.get_tile_image_by_gid
        for layer in self.tmxdata.visible_layers:
            if isinstance(layer,pytmx.TiledTileLayer):
                for x,y,gid in layer:
                    tile = ti(gid)
                    tile = pygame.transform.scale(tile,(32,32))
                    if tile:
                        surface.blit(tile,(x * self.tmxdata.tilewidth, y * self.tmxdata.tileheight))

    def makemap(self):
        temp_surface = pygame.Surface((self.width,self.height))
        return temp_surface

Is there a way of "zooming in" on the sprites in order to get the expected look?

You need to offset the tiles with the scaled size, not the original size. Currently you render at (x * self.tmxdata.tilewidth, y * self.tmxdata.tileheight), but instead you want to render at (x * 32, y * 32).
