Are my eyes too big for my face, or is it all in balance? What surgery do I need for better balance? (photos)

The photograph taken from above suggests problems with the position of the lower eyelids and the attachment of the ligament in the outer corner.
However, the photograph where you are looking straight ahead shows a balanced overall appearance of the palpebral aperture with only a fraction of lower position of the lower eyelids.
It works well with the general appearance of your features and is probably best left alone.
If you want to change slightly the contours around the eyes, you could consider nonsurgical treatment with botulinum toxin type A to raise the outer corner of the eyebrows. 

Every person's anatomy is different. There are changes that are possible depending on individual anatomy and desired goal with consideration of risks. See an expert.
