Modeled in Blender 2.77
Comments and critiques appreciated…
Awesome atmosphere with the sand/dust in the air… and looks very real
how much was done in photoshop or was all of it done in blender?
Well done, i like this atmosphere! but cactus realy needs subsurf modifier 
and sand waves could be a bit sharper
Thank you all!
@boko600 Just the dust was photoshopped… I originally had it made in Blender, but my 2 GB PC couldn’t handle the extra memory consumption…
@YuraUT Thanks! And I agree completely… I unfortunately took the subsurf out of a lot of things, because it was really struggling to render the scene… I actually was crashing every 3-5 minutes… Lost a lot of work in the process 
cool) , but I think the sand is too smooth , I’m sorry if you do not put it clear , I do not know very well English
Yes, I agree with that… When I did it, it was fine, but I changed my lighting in the final render, and the sand got overexposed… Since it took 16 hours to render, I didn’t have time to render it again… Thanks for the comment, and sorry for the late reply…
