Gun Criticism Needed

Sammy101

Hi I am making a 38 revolver specifically inspired by DietCoke who made a god tier model. Reference isn't down to the exact dot, as I was pulling in some details by imagination and other references. But that's not too much on what I am concerned about. With the revolver grip, I don't think it looks quite right. Something is very off about it, so I was hoping someone here could point me in the right direction. I plan on NDOing in details, any criticism is greatly appreciated.
