I dunno dude, the sun is going down in the background but the guy has sun on his face and the horse has a reverse shadow. the car doesnt fit in, nor do the bushes. Concentrate more on detail and you will make some fine entries

EDIT: you already have made some fine entries :S what happened here ? Reply »

If the sunset is behind, I think the shadows are wrong... Reply »

Shadows r wrong, car should b bigger since it's in the foreground, horse+ man smaller...if the light is hitting from the back, the shadow should be cast to the front...GL Reply »

These sources will never work together. All different light sources and perspectives. Try to do comparisons to the original source images and see where the light is and where shadows fall, etc. Reply »

The horse looks like it's floating ^^ Darken the sand around the feet to make it look more grounded and it's weird how the shadow is on the wrong side if the sun is coming directly at us, don't you think? Reply »
