Deformed Mesh After Fitting (Want to know possible reasons and ways for improvement)

[soni-H]

Hi,

I am a student exploring 3D vision and facial parametric models. I have had a hard time fitting flame parameters on my mesh and I guess I am missing something very basic and essential here.
The mesh that I am trying to fit has ~38K points and ~64K faces. And it looks like the following on surface reconstruction using ball pivoting filter from meshlab.

The mesh surface is not smooth as it is in the example mesh. However, I tried fitting the above mesh and clicked 51 landmarks using PP module of meshlab. The resulting mesh is deformed and looks like I am missing some very basic things to have received such a mesh as output.

I'm attaching the mesh and picked 3D keypoints here. It would be a great help if you could spare a few minutes and have a look at the mesh/landmarks.

Is it because the input mesh is not a good enough or there is some issue with the landmarks. Also I have been setting up scale_unit as 'na' so far.
