Firstly, Your lawn ornaments are nice, don't waste your time thinking about what one Yahoo's opinion of your ornaments is. You can certainly add on tom your existing pond by either digging your pond next to your existing pond and dropping the wall between the two ponds about one foot as we did or seperating it and placing the new pond where you want. We have a seperate 200 gallon biological pond 18 feet away from our existing pond. The two ponds are connected via underground tubing. If you look at this video, you'll see the biological ponds waterfall in the back (located to the left of the walking stick tree) in the beginning of the video and at the end of the video. Also keep in mind the dog leg section of the pond (the 1998 add on section of the pond) is 6ft w x 13 ft long. That is the part that was added on with only a one foot drop connecting the two ponds.

I just want to give you confidence that it can be done by either hiring a pro or taking it on as a DIY-er...you did a good job so far.
