Good stuff, nice location for the shots you’ve taken here. I particularly like the competitive implications of #1 which make the second too more run of the mill. Looks like a nice location kayakers or not.
If anything the kayakers look a little blurred presumably due to too slow a shutter speed ?? It looks like the environment is quite dark though which could explain that. Not sure what ISO you were at on these but could you have gone higher ?
I like the first one as well, if you have a zoom I think there’s a case to try having the kayaker & kayak filling the frame with the foam of the water all around and cutting out the background completely. I’d say the facial expressions of the kayakers would be good.
Yes the second one is what I was thinking of, having the water splashing up around gives the image movement. For the first one, as the water isn’t as wild you could leave a bit of space to the left to imply the movement of the kayaker. :)
