That doesn't look too bad, just looks a little unfinished. When I was shaping my frame, I had a bit of trouble trying to get my trigger guard of equal thickness on both sides, once I reshaped it. Trying to make it look like it came from the factory this way is the idea, after all, while making it fit you. Yours looks a little wavey, or is it the picture?
With some practice, you can cut a border around the stipple, and make it look like a grip addition, and not like you poked holes in the grip.
Some of the best work I've ever seen was done by cold bore customs, this is where I got the idea. Great appearance.
