Your Realtor can advise you, but in the end it is you that must be happy with the price. If you are willing to wait for an offer and you seem to have done your home work then stick to your price for now. Have your realtor keep you posted on the sales of similar homes. That will tell you if you are still on track.
The right price is what a Willing buyer is willing to pay a Willing seller. If you are not hurting you do not need to deal with someone that thinks Texas should have been hit like California.
Your Realtor is only concerned that you have not had an offer, we usually say that is there is no offer with in so many showings (differs in different areas) that the house is overpriced. May or May not be true in today's Market - I have people looking too high, they need to come down some. Lenders are tightening up on income ratios.
