Pretty good except for lens flare...

I very seldom use lens flare- just felt it would add to the composition this time.

the lens flare makes it hard to see the edges of the cliff. Takes away from the focal point of your title

I download the brushes long ago and i don't remember the source .... sorry

Unfortunately the image will have to be removed then... Still.. nice lighting on the ground and on the snowboarder.

Really sorry that I do not remember where I downloaded the brushes ... I downloaded them in september and not remember the site ...

hw can i do the same effect without using already made brushes? will like to learn it

1 way - Staining brush in whatever color you want Ctrl + E to get them mated then Ctrl + J to copy them then go Filter> Blur> Gaussian Blur and puts about 8 or 9 and then connect them with Ctrl + E then copy them with Ctrl + J again Filter> Blur> Gaussian Blur to this time the value is 250 if the brush is less then the value will be less .. .... Method two. No color brushes and do the same things I've described above in the text. Then go to Layer> Layer style> Gradient Overlay and put a gradient want

The first "flash" could be on 33% opacity, the 2nd on 66% and the third on 100%. Would give a nicer motion effect I guess.

It's simple but a clean chop and very convincing but just a small nitpick, in high res, the snowboarders edges just need a little bit more attention, maybe feather 1 pixel when cutting with polugonal lasso tool Still well done

I think the shadoe is very unnatural, and the repetition in snow patches is obvious, even in low resolution, i suggest working on those.I would also suggest adding a bit of motion blur to the snow

agreed, put some motion blur on the snowflakes. also, experiment with different flake sizes, to help create depth

Thank guys hope this is better

Try to find a tutorial on the internet for how to create snow in photoshop, it will definitely help you to improve this. I also suggest you sharpen the background, because the snowboarder has now been blurred completely. As for the shadow, it still looks unnatural, i suggest you remove it and try again, just a bit of low opacity black paint around the edges of the snowboard and not the whole person. Good luck.

Ok here is a remake. Thanks all

It's totally different now...
