I'm not a rabbit "amateur expert" just yet (having owned buns for just 11 months now). But I think that the urine in the photo looks normal. (My girls' urine ranges in color from light-yellow to deep rust. As Pipp mentioned, things are likely more normal than not if it has the normal viscosity of urine.)
What throws me more is the consistency of Smitten's poops. In the photos of her sitting on a towel, they look clumped and mushy. (Are those cecals that she possibly smooshed down a bit?) Then in the urine-focused photo, her poops range in size and some are misshapen. (I know about misshapen poops; my Zoe has them pretty much all the time.)
I hope that the tests reveal an effective treatment for Smitten.
