How to improve the clarity of printing details

Hey, I recently attempted to create a Yoda model, but I got stuck halfway through,could you please help me?
First, I created with computer-aided design software. It’s like building with blocks, piecing together Yoda’s shape bit by bit. Once I’ve got the model, I converted it into an STL format.
and I checked the model to make sure everything’s perfect.
When it’s time to print, I choose pla filament and then let the printer do its magic. here comes the problum,when printing to details, such as Yuda’s hands, she suddenly becomes confused and the details are not as clear as it was,what should I do?

It sounds like you’re really close! The issue with Yoda’s hands likely comes from layer height, print speed, or cooling. Try lowering the layer height for finer detail (like 0.1 mm), reduce print speed, and make sure cooling fans are running properly for small features. You can also add supports or slightly increase infill to stabilize those thin parts. That usually sharpens the tiny details nicely.
