I have to agree that the scales are to thick by about 1/3 on each side. The question is does it fit your hand comfortably? If it does and you plan to keep it then your doing great. If you want to sell it, many customers would want a more balanced handle width.
The front of the handle also looks to thin, not as in wide, but vertically along the blade. This is just my personal view. Most people look for balance in the overall design of a knife they want to buy.
The work and finish look good.
