Your floor looks amazing and I know you will love it!!!
I love my stained concrete floors - we built on an 800 sq ft addition to the back of our house five years ago and we left the floor concrete and stained it ourselves. We were so lucky because it was "virgin" concrete without ever having carpet or anything on it - and it still was a lot of work - but not 1/4 of the work you did.
My hubby and I did it all ourselves - but we didn't score the concrete. I love the variation in color and I love my cracks too!
It is so great!!! We have had it for five years and we should have put down a new coat of sealer about 3 years ago - but my hubby got sick and we just didn't have the time, energy or money to do it. I am so lucky on this one though, because the pee stains DO NOT show - even though they do soak in if not found in a timely manner. But they do not leave a stain at all!!!
My color is much the same as yours - and I do love love love it!!! Anyone thinking of doing this should seriously consider it. Yes, it is a lot of work on concrete that has had floor covering - but if you are building a new home or adding on - it is very inexpensive, if you do it yourself. And if you ever sell the home and the new/prospective owner doesn't like it - well you can just slap in carpet, etc!
