Wait...wait...wait wait wait wait wait...I made sense?!?!?!
HOLY CRAP ON CARROT!
Right now, I still think you're biting off more than you can chew. Setting up scenes is important, learning composition is a necessary trait. But, I think you should start much simpler. To learn composition, just draw some simple, loose line drawings, very small. It's easier to fill a thumbnail with information, than a whole page. When you draw them, don't be afraid to be loose and abstract. Find what works and what doesn't. Work with foreground, middleground, and background. Work with positioning elements on the page. Play around with the Rule of Thirds.
Remember, especially now, to think simple. Just follow the K.I.S.S. method. "Keep it Simple Stoopid".
Also, I saw a preview for Shadowrun...doesn't look cyberpunk at all. It look like Halo with different characters. Very un-cyberpunk. Cyberpunk needs to look 80s, goofy poofy hair and large shoulders, lots of wires and techy stuff all over, too. Or, at the very least, a belt pack machine...like Hiro Protagonist's.
