Khajiit in Skyrim should look like this http://www.furaffinity.net/view/5150735
That body structure would work for a Cathay-Raht (just need to change the tiger look into a jaguar look), who are the largest and strongest of the bi-pedal sub-species of the khajiit. However, they'd probably be landed in the same area as nords, orcs, and redguards, further limiting the only 2 sneaky races as is (Suthay/Suthay-Raht khajiit and bosmer).
And here's the Argonian!

1. Head tilted a bit forward
2. Looks like beast feet.
3. Hands more beast like.
4. Tail more defined.
Now that's an awesome looking argonian!
