Hi Sally,
That's good for an 'on-the-run' capture.
I do feel you could crop off nearly 40% of the image on the right and not lose anything significant though, given the way it is facing.
More generally:
DoF - there's
never enough - I have a similar lens and just shoot everything at f/16, only going wider when I absolutely have to; e.g. because I can't raise the iso or slow the shutter speed any more (without spoiling the image in other ways).
In controlled (and static) conditions,
focus stacking offers a solution. We have many members who are good at this; FrankMi and Mat (flyingsquirrel) to name but two (my apologies to anyone else I missed)
In the field, that's unlikely to be viable, so adding light, by using flash (ring or otherwise) is about the only practical method to allow you to use f/16 or f/22 on a moving subject and maximise DoF.
Have you seen our tutorials?
