As others have mentioned:

• Dry your filament. Stick it in the oven for 2+ hours on minimal settings. If you have a fan in the oven, even better.
• Tune your printer. Do a temperature tower with your dried filament. Lower temperatures might improve quality at the expense of lower layer adhesion. Do a flow calibration routine. Overextrusion can also have effects like this.
• Slow down the printing. Increase minimal layer time, which might have an effect. If it’s original E3, it has relatively poor part cooling, which can be compensated by slowing things down.

Nothing wrong with Ender 3, if you thinker enough, you can get results as good as any other printer. But it may require tinkering. The model that you’re printing is difficult with FDM printers of any kind. It has thin, delicate parts with steep overhangs. It can look better, but it’s gonna be hard to achieve. Resin printers are definitely a better choice for this, but you use what you have.

Don’t dry filament in the oven. Simply put the filament spool on the print bed, set it to 60°C (PLA) or 70°C (PETG) and cover it with a cardboard box to trap the heat. Poke 3 holes in the box to lead damp air escape. Let it cook for 2-4h, then flip the spool and wait for another 2-4h. Store in air tight container with some silica gel to keep it dry.
