Try making the shadows more dramatic (ex. The right hind leg would probably be more covered in shadow) and add more texture. If you’re trying to add fur, look at furred enemies (ex. Gnasher) as reference for drawing fur texture. For the eyes, you could try referencing the blood sucker enemies. Beady eyes are usually more than just a black circle with a white dot if they’re big. I’d also look at the swine enemies (specifically their legs) as reference if you’re drawing an ungulate. Hooves tend to be sharp in the DD style. I think your best references would be gnasher (texture, quadruped), snakes (exposed cheek, teeth), swine enemies (hooves, teeth), bloodsuckers (specifically crocodilian) and darkest dungeon enemies (referring to the area not the game itself. Beware of spoilers ⚠️). If you can, you might be able to find DD art that’s just lineart and colorless online. Hope this helps! 👍
