Stone(d) Wall, Normal Map Fixing

So I decided to project the normal map from the high poly model I created onto the low poly in 3Ds Max. I began cleaning up the base mesh and put the normal onto the model but something was wrong look in the image below! -

I was having an issue with the way the normals were projecting, and this was even before I began cleaning up the mesh, After my cleanup work was done as shown below

I had to go into photoshop to clean up the messy normal map. I started by finding all of my problem areas in the normal. You can see the original normal here and I circled an example of the normal map bending that was going on in the image -

As you can see, warping was happening in certain parts of the model. I opted on fixing this problem by using brushes to create straighter lines, then I went on to take parts of the image and fix up the normal map like you would if you were photo editing. I ended up with this below -

In the end, voila! A much better normal map on the model -
