Use the Polygonal Lasso Tool (L) to select the contour of her body, especially the arms to remove the black matte on these areas. Click the second icon at the bottom of the Layers panel to add a mask to this layer and we should have a similar result like below.
I want to change the look of the model a bit. Make a new layer (set as Clipping Mask) and use a small brush with the color #27243c to paint on the reflection of two eyes to remove them. Name it 1 or whatever you want. Hide this layer and on the model layer, use the Lasso Tool to select the reflection of the left eye and hit Ctrl+C to copy this part. Make a new layer on top of the layers and set as Clipping Mask and press Ctrl+V to paste the reflection into it. Move it to the higher position than the original one and turn on the layer 1. Duplicate this layer to make the reflection more visible.
Do the same with another eye.

Create a Curves adjustment layer to bring more light to the contour of the model. The selected parts show where to paint on the layer mask.
Make a new layer, change the mode to Overlay 100% and fill with 50% gray:
Activate the Dodge and Burn Tool (O) with Midtones Range, Exposure about 15-20% to refine the light and shadow on the arms, face and back of the model. You can see how I did it with Normal mode and the result with Overlay mode.
Open the wing image and take the wing part on the right of the back to add to the lower body of the model in the main document. Use Ctrl+T to rotate it as shown below.
