Appreciate the comments. Those shots are all with my 7DmkII and the 6D is new so was looking for anything anyone may have to offer.
Nothing to add - it's a relatively basic camera compared to the 5D4 or 1DX2 but, combined with any good lens, it can hold its own even in poor light. Or should I say, especially in poor light. I find that it can focus in near darkness - this is especially useful if you are using flash/strobes without a modelling light or poor focus-assist.
