Retro RTS game idea

Four years ago, I ended up in the hospital where I lay and could not do anything. All I had was a sketchbook and and pen (and some history books).
I had an enormous desire to play some old strategy game, but it was not possible. So I "made" one.

Here are some sketches I did at that time.
I have a fancy story and ideas how the game could work.
Unfortunately, it is not possible for me to create game by myself.

This weekend I drew the main menu in photoshop.
I'm still not a friend of digital painting and and I can not do it at all. Its too hard for me...
(any advice or tutorial I welcome)

PS: Excuse the poor quality of pictures. Everything was drawn from my head...
PPS: some updates
