Is this the “monster” you referred to in my thread? BAH! I think this could turn out to be a beautiful image. Really, I’m just going to repeat what pap87 said and say it just needs a little more contrast and details(darker in the corners of the mouth and nostrils, under the eyelids , the pit between her collarbones etc)
I like how the Egyptian queen is turning out, especially the attention you have given to the background. The drapery looks lovely!
Something I try to do is try and imagine the blobs of paint I put initially as a lump of clay. I try and sculpt the face out of it. I think it generally helps to try and visualise your image as a 3d image and place your darks and lights accordingly( if I want a depression in the clay, like the the eye socket for example, I’d put some dark tones there. Then I’d put lighter tones for those parts I want to project out)
The brush I use mainly (and almost all the time) is a Photoshop default brush. If you see the list, it starts with the hard round, then goes to the soft and then after the largest soft round brush (no 300 I think) it goes to brushes that are the hard round brush (I think) with the opacity set to pressure.I just use those, I must start using more texture brushes
If you don’t find it let me know and I’ll upload it for you 
edit :Here you go.
One more thing to remember is that the background always gets reflected in the face, mainly in the darker tones. So if you’re stumped about the colour to use in the shade, just colour pick it from the bg and paint with low opacity, gradually building it up till it looks ok 
edit: I just looked back at your WIP thread. You’ve come such a long long way since …March! Your progress is really phenomenal. Keep drawing and you will get much better! I’ve had 4 years of life drawing/painting and I’m still stuck here
