Are my eyes too close together? (photos)

Does not look as if your eyes are abnormally spaced based on the remainder of your facial features. If you want to measure objectively, you can get a sliding caliper or any other measuring device and check the distance between your pupils. Average is on the 60-62mm range. You can also measure the distance between the inner corners of the eyes which is 1/2 the distance between the pupils (30-32mm). The distance between the inner corners (30-32mm) is also roughly equivalent to the distance between its inner and outer corner of one eye.
