Is my forehead too sloped?

When speaking about one aspect of the face it is important to consider the face as a whole. Some procedures can help or hurt facial harmony. If you feel like your forehead is too slopped there are procedures that can be done to improve it such as an implant made from a CAD 3D model based on a facial CT scan. You can also consider a fat transfer, or Sculptra implants. The best way to determine if your forehead is too slopped and what procedures to go forward with in order get the results you want would be a consultation with a board-certified facial plastic surgeon. 

With a retroinclination of the forehead approaching 35 to 40 degrees that would be considered 'too sloped'. Have computer imaging done to show your forehead with less inclination and see if that looks better to you.
