These are my first two shots without really thinking about the composition too much.
Interestingly looking at the two sets I prefer different orders. Goose shots from most favourite to least in terms of what I think works : 29>31>28>30. Poppet shots from most to least favourite : 34>33>32>35. I like the goose all the way off to the right so you can see the full spray and it gives it room to travel forwards into. With the poppet, a little off centre works best for me and with it looking off to the left it makes more sense to me to have more space on that side. Having the subject at least a little off centre makes it stand out more against the background. The unbalance really works I think.
