Nice work, you seem to have a good sense for angles and compositions. 👍
But one tip, lower f-numbers, to get a nice DoF.
But the one tip that you need to know is to use panning mode 2/3 and a low shutter speed. I can assure you that the last picture will look "better" with panning mode 3 and 1/60.
Otherwise, keep it up.
I see you're a quick learner.
I like the conveyed sense of movement. But I have to ask, what's the deal with all the artifacts?
