Help with trying to print a larger minifigure from HoMM with Ender 3 (beginner)

[FirePaladin]

So, basically, I recently started printing with my Ender 3. My first try was a HoMM3 castle, which seemed to be ok, only a little too fragile. Second attempt was a dragon from HoMM5, but due to problems with the Z axis (I fixed that after), it was basically full of overfill. What I am asking for is if someone can help me a little with the settings for my next print (infill was changed from 35 to 25 here):

Here's the project file, from Cura: http://www.mediafire.com/file/e2rc53...eDemo.3mf/file

What exactly are you trying to fix now?
Are you still trying to handle the infill or is there another problem?
Also, what filament are you printing with?

PLA. Infill isn't a problem now, but I just want to hear from the experts what settings should be changed (also, thanks to all who downloaded the file for personal use. It's very polite, especially since nobody told me and I attached it to get help).

EDIT: For everyone who DID print the Titan, can you tell me how it went, and maybe attach a photo?
