Hi, I removed the background and made a mask. Do not know what to do about the inside parts next.

Hi, looking for some help.
I used the pen tool to remove the background and made a mask. But there is still parts of the background inside the image. I do not know what to do  or how to proceed next because I already made a mask. Do I apply the mask to the layer and then make new selections and mask with the pen tool to remove the background in the picture?  Please see attached files:
1. image background removed with the pentool and made mask/selection  
2.image of what I want to remove but do not know how to proceed next

@Paul330625612y7w select the mask and make sure black is set as the foreground color and then paint on the area's you want to remove with the brush tool

Thank you for the reply.  Will that leave jagged edges?  or is it better to use the pen tool, make selection, the fill with black on the mask for those areas?  or just brush with black and then smudge?
