Ah, I see what program are you using? Usually smudging is not suggested for more detailed area like the face it's rather suggested use a low opacity layering and on-canvas blending technique.
And thanks, You can see the full piece in my avatar here on my own critique thread: Most recent painting (critique please?)
That newer one looks good, looks like you are paying attention to detail on the face. With horses, the most detail is usually the face and legs.
Ps: I didn't post that a 3am, lol, it think is more like 3pm, idk
