Big dune fan here.. so you don't mind if I seriously crit it do you? I think you should have spent more time on the worm than you have on the background?? Add maybe some teeth to the worm, work on the three segmented mouth abit more, or perhaps go for the traditional idea of the huge circular opening for a mouth. The worm is your focal point of your picture and yet I'm drawn to the detail in the back ground. And the fremen usually ride the worms in a straight line on it's back.. perhaps draw some small hooks from the men as well
Anyways all is good
And thanks for giving me a few memory flashbacks into my child hood.. not that it was that far gone or anything...
