Things what I likes: The sculpting for sure. The texture of the hide on the brown one/ the cool scales and horns too. I also like the colour and shading on the brown one. The war paint is nice too.
Where to work more: The red one needs work on the painting. The colour used to shade isn't giving enough contrast or maybe it's just too muddy. Red is a tough color though. And the base, needs a bit more highlighting and as much attention as the minis. Kinda feels like ya mailed it in there
I see a lot of promise in what you are doing and think you just need to practice and refine the techniques you are using. For example, don't just apply the wash everywhere and let gravity take over, try to put it where you want the shading and build it up in layers.
Keep at it and I look forward to seeing what else you have in store fro us
