Roger ---hey the concept art looks cool. And I get the ideas you are thinking about --so nice job. Looks like cool a fun project to work on. And I understand how you feel about posting things here. I have to admit it seems a little intimidating ---(I have not posted anything myself ).
And sometimes wonder if it would not be better to have a new user WIP folder where less polished , less accomplished things could be shown and folks might feel a little more at ease doing so. For I think less WIPS get posted right now for the fear factor of feeling not ready for prime time as it were.
But let me say --you are , so keep us informed of how this project grows and thanks for Posting!
