More or less similarity to show style and fur is matter of taste, and possibly there are some your fans who prefer more show-style variants edits than more fluffy yakovlev's variants.
Still, better to keep attention when you change the curvature of countours and shadow edge of big shapes. You can remove details, still it is better to keep big shape created by details. And avoid change S curves to C curves or straight edges when possible or changing the curvature too much. Also better to avoid change of subtle smoothed corners to totally smoothed curve. It is possible to smooth some corner more and avoid total removal. And keep attention to avoid shape changes between curves and negative space between shapes, this affect character appeal.
Sometimes it is impossible to keep these shapes and curvatures. For example, it impossible to keep big shape of checst/neck without fur, still possible to keep smoothed corner of this big shape. But it is better to keep them when possible, and be aware when you have to remove them. Actually show style keep many of these features, but in very subtle smoothed way. Hard (but possible) to see conciously, but they affect character impression subconciously.
Also cylinder and cube drawing exercises can help to make better 3d depth impression of 2d shapes. Even in edits. I have some tutorial for cylinders/legs >>2286285 :]
Sorry for the un-asked critique, hope it still better and more constructive than these many "why-are-you-doing-this" reactions.
Anyway, I respect your determination to avoid whining on pony fur and just fix with your own hands and I respect original artist consent of edits and experiments
