Seoul Metro Train Designs

 I've been working on some designs for some trains. There is a competition coming up and I've been wanting to participate in it. The theme of the competition is on trains. I've tried drawing various train designs but some of the drawings felt a bit too cliche so I took a design direction where the trains look more livid.

Now I have to move onto the bigger picture and start on the project. I'm still divided on whether I should pen and ink the piece or not... I do like the strange, light quality that the pencil gives but the pen and ink does make the pictures pop up more.
