Wow. Fast reply. On a Sunday. Thought you'd be in church!! 
Thanks for sharing. I like the way you caught her head in the light wash on the wall behind her as a background enhancement. (I assume you would likely crop the light fixture above out.) Yes, tricky lighting.
If you were to compare the Tamron 24-70 to either the Canon 24-70 or the 24-105, how would you rate it with regard to your real world use in these type situations? In other words, for someone who owns those lenses already, what was your impression of the Tamron 24-70 difference in actual use? Good, bad or otherwise? I'm trying to decide if I should spend the money (or not) in order to achieve a potential (but unknown) XX% improvement for the cost. I hope I'm not asking something directly covered in your review. If so, sorry!!
You caught me before service

I've prayed, preached, and prayed some more...so back to photography until this evening
The 24-105L has perhaps the best focal length of any EF lens (unless you count the 28-300L, which few people do). That being said, the 24-70 focal length is obviously a very usable one for general purpose. I found I stopped using my 24-105L after I purchased the Tamron, and eventually sold it. The Tamron color is more appealing, the fast aperture adds a lot of different creative options, there is much less distortion, and the VC makes it one of the most handholdable lens out there (perhaps bested only by Canon's new 35mm IS). I would definitely recommend it over the 24-105L.
I haven't used the Canon 24-70L in either variation. If money is no object and you don't need the VC, I would go for the 24-70 II - it is considered one of the top zooms ever. The Tamron adds the VC of course, and is optically superior to the MKI and slightly inferior to the MKII. If you don't have (or don't want to spend) MKII money, I would definitely recommend the Tamron. It is my current go-to lens and spend the most time on my camera despite having a bag full of great lens.
P.S. Color renders warmer in the Tamron vs. the 24-105L. Whether that is good or bad depends on your preference. I personally like it.
