glcm angle issue

Hi I have a quick question for you. Since you already worked in GLCM and calculated glcm for 4 directions.
So I am trying to calculate the texture features of my 1 image using GLCM. Now if I use these properties properties = ['contrast', 'energy','ASM', 'homogeneity', 'correlation', 'dissimilarity'] and calculate GLCM in 4 direction angles like [0, np.pi / 4, np.pi / 2, 3 * np.pi / 4] then I get 4 *6=24 feature values. Now my professor is saying 24 features are not enough for the feature selection so calculate GLCM in more directions to get more feature values like previously my directions were [0, 45,90,135] now he is asking me to calculate in [120, 180, 270], etc just to get more features. But everywhere on google, I have seen people are calculating GLCM in the standard four directions that is [0, np.pi / 4, np.pi / 2, 3 * np.pi / 4] so is this correct if I calculate GLCM in the other directions which he mentioned?
