Sorry but this is just bad advice +on top of bad advice, baking, then removing geometry, then editing uvs? Editing your geometry after you've done your bakes will alter your mesh normals, and generally cause smoothing errors. It is not recommended unless you can make sure the mesh normals stay exactly the same. It is best…
Hard to say without knowing exactly what problems you're running into. I do a lot of hard surface stuff, and rarely ever find the need to edit normal map errors out in photoshop. Most issues can be solved by good planing, explode baking and understanding how your mesh normals project out from your lowpoly mesh. More here:…
A couple of those look like slight projection issues because of your lowpoly topology. EQs thread should answer those questions: http://www.polycount.com/forum/showthread.php?t=81154. Basically those flat surfaces are getting projected at different angles and it is hard to get the detail on them to pick up correctly. You…
How are the UVs? But hey, check out this thread: http://www.polycount.com/forum/showthread.php?t=81154 It could very well be the issue. Essentially, any deviations the low has from the curvature of the high causes distortion. It may or may not be your problem.
The angles on the front of the hoofs are very steep, cutting in a support loop around that harsh edge may help. This thread goes over the concept in more detail: http://www.polycount.com/forum/showthread.php?t=81154
