I am extremely surprised with this painting, especially the apparent theme behind it, and the overall composition and structure of it.

I would first like to compliment you on the composition of this. Your use of lighting and colours really give this painting a grim feeling that appears to be closely related to the theme, which on a way appears to be some sort of destruction of nature, seeing as how you incorporated a person walking down the road of a seemingly empty area with the exception of the factories up ahead.

This painting reminds me much of the book "The Road" For some reason, though it doesn't seem like this painting was meant to be apocalyptic in any way.

Overall, this is an astounding painting, your use of colours and lighting give real life to the image, and provide a pleasing viewing experience for the audience.

first of all i would like to say its an awesome piece
now lets get to business...

the positives:
The whole scene is so dramatic with a post apocalyptic feel to it...and the sky looks very suitable, all those clouds and the smoke flowing through polluting it makes a good contrast with the sun shining from the other side maybe gives some hope for a brighter tomorrow ( if thats not sarcasm u meant by it )
and the factories r blended very nice with everything else...with a perfect dusty wind going around the whole scene...
You also made a very nice touch to everything by adding the model walking toward the viewer...and that particular mjranum model is a brilliant choice! and i love the way u made her shadow also...really nice

the negatives:
just one thing...the focus throughout the piece here would have been better if everything was in the same direction....translation: the end of the road has a left turn...its unnecessary in my opinion...if the road was straight toward us it would have been a stronger effect....

i hope this was useful to u
