So now we have the other leg, pieces 51-63. I managed to warp the feet so they will not sit flat

Guess he'll have to be standing on something...:nailbiting:

This is another angle so you can see how the parts fit. not all of the tabs appear to be designed to be glued together - but rather just overlap.
Since they just overlap there is some space between the pieces - so I went around the edges of the white areas and colored them in with the black marker - about 1/8 of an inch to ensure the white boarder would not show when assembled.
As you might be able to see in this shot, each leg is really held by one flat tab as shown with the blue circle. The red stars show the other "tabs" that are curved and really are not glue-able.
To get around this I glued the edges where the parts met the best I could- otherwise lifting the model would result in the legs dangling by one tab. If it looks like what I glued will not suffice, it will be easy enough to glue some strips of paper across the "seams" on the inside of the model.
And assembled. Special guest included for size reference.
Here is a view from the top going along the back where the dorsal fins will be located. If I was a "master" I'd cut some wiring holes now and put some blue LEDs in there since the final fins do not close completely at the top - and add a sound module for the roar of course...and a nice paper craft base...and a solar turntable... but back to my reality...:coldfeet:
And standing from the back..
More to come...
