After reading my I.O.R I finally get what I'm suppose to be doing. Since I was new to the whole landscape field I was just trying to draw them rather than adding style('s) into it.
I've Looked into Military art and Naive Art. Which are huge contrasts, Naive being the "Childlike simplicity" where as Military art being the more realistic, the main thing I liked about Military art was the old effect the paper has. I want to Mix the two, have unusually high walls, with the colouring of military art.
