The colors, back lighting and motion has come out very well in the pan shot. The colors are impressive.
My thoughts , a bit more space on top would it make it different?

The background looks very interesting, lovely colors there and I would love to know why do you call it the Art of Running ? The art was created by you and not the boars I guess, am sure they did not notice the rim light , it was you who saw that, lol. Kidding man, Interestingly, I do not why, I have never photographed a wild boar, even when I have got hundreds of chances, something happens to me, I simply can not shoot boars. One needs to see if it's me who's boring or are they too boaring .

the color....the whole pic is like a painting....

Ganesh, This is beautiful. Some how I tend to like without grainy effect here. I kinda like smooth colour spread. Cubs running effect makes it interesting.

Looks like a water color painting. Back light and slow shutter are adding a lot.
A very tough subject, presented extremely well. TFS.

Interested to see if there are any abstract frames.
