A little catch up here Phil...
Loving the fish pic, captured the colours superbly, and not easy to judge shooting towards a tank. The crazy angle of the snow shot really makes the pic for me. It's a different perspective and a little belter

The sunset on Day 37 for me doesn't really work, sorry fella

, the blown out part of the river in the bottom right hand corner, and the branch on the bottom left are too much of a distraction, but it's definitely one to maybe re-visit at some point. The machinery shot is really nice, works for me, and suits mono well

Day 39 is a corker, really vibrant colouring, great dof and sharp detail too. Great shot of the bird too, again great detailing.
Today's toy shot, works really well, good dof and works brilliantly against the background. Regarding your question about the on camera flash while using off camera, I'm sure if you turn the power of the on camera flash right down to as low as it will go, it shouldn't make much difference to the shot you're trying to get using off camera flash
