Firestar's First Death Redraw

Clearly, you've improved a ton! Your grasp on color, design, and overall scheme is much, much better.
I especially appreciate the attention to detail on Bluestar's pelt, with her typical scar showing.
However, there's still some things to improve.
While your anatomy has gotten better, I would still practice the basic shapes and proportions. One example would be their paws, which seem to be nearly as large as their heads, especially so on Firestar.
Another thing I would recommend keeping in mind when making group drawings, is to give more variety in their facial expressions and body types. Especially in the back row of cats, as they all seem to be the same model with different colors slapped on, all making almost the same exact emotion.
Lastly, I would mention the wounds on Firestar. For scars, using only one color will suffice, but for fresh wounds, I would change up hues and shades.
