To me the main object isn't the tree but the mountains behind it

This can look so interesting if the breads looks livelier. Now the breads looks really pale and thin

For such a bright light source, i think you should make alot of shadows

Fantastic color!

I find it weird when the plane looks abit blurred when the model is sharp and she is standing right next to it. I also think that you should lower the opacity of the shadow

The shadow on the right is too obvious to me

The color of the portrait and Gandhi statue is too different

Is the stock for NASA free to use?

I think you might want to link your sources and do a SBS

The only thing that i dont like is that the render is so high res while the background is full of noise

It is so much better Author nicely done

I understand what you try to achieve here is motion blur. As a photographer that have shot many moving things (including this kind of act in a circus) theres no need to have a drastic motion blur because the performers doesnt move as fast as racing cars, what you need is motion blur in some part of the body to make it looks more realistic

I think the glass needs a fisheye effect

I feel that the blur is overdone because i cant see the beautiful picture from the stock

I dont like the filter and the gem. The rendering of the swan is not quite smooth to me

i feel that the picture is a little too cartoony

If the exposure is darker it would be better
