Is there any way to create a face out of these selected and enclosed edges in the screenshot? I have tried using the F key but the face overlapped part of the model. Any help is appreciated. :D
You definitely need more then one face to fill that side, I used six.
The best way to fill that shape would be to look at your model, and think about what edges you need where, then decide what faces should go where. You should be thinking about edge flow, and face loops for your entire model.
