Hi basset,
again, we need a bit more info.
For example:
What kind of resolution do the images have.
What do you not like? It doesn’t look too bad in my opinion.
What is your goal?
A wireframe view would also be good.
What you cannot expect is a model that is perfect on the pixel level. What I mean is that the geometry will always be a bit wobbly if you look at it with the full resolution of the images. So you need to take images with higher resolution to get a good geometry. Or you can retopologize. There are many variables…
