Your coloring and details are both pretty good.
Here's how you could improve your art. (imo)
Once in a while, you could try to vary your character poses more (yeah, I know: more work). As long as each poses are consistent with each other and what is depicted to happen, it would give a better feel of continuity than a feel of "time being frozen".
You could also consider looking at lighting techniques. Front lighting tend to flat things up (even with good blending), and some of your shadows could be more consistent with the overall scene lighting and the rest of the subject.
Again, its only the humble opinion of a fellow artist, and its up to you to consider what I said or not.
That aside, keep up with the good work! :)
I really like the Taimanin one, too.
On a side note to >>25372
Because eye rolling requires muscle contractions, it can only occurs while dying, not on death. At that point, they usually rest in a 'glazed' or 'dulled' expression… Unless the point is to make things silly on purpose, of course (like a cartoon, or like N.Dofline who does that well).
