I’m not an expert of this type of image but I think you have done well with these.
#1 is a fine looking headon image with the subject sharp and the background nicely blurred.
Theres a great sense of speed conveyed in #2.
I did feel the framing was a bit tight and that maybe a wider view with a liitle more space to the
front of the subject might have made for an even more dramatic photograph.
Good sense of speed in #3 too although I had the opposite thoughts about the framing.
I would suggest cropping out the fence at the top and about an inch from the RHS.
Only my inexpert thoughts but I thought you deserved some sort of reply.
