It was the last day before deadline for a monthly challenge (on deviantART) and I knew, I would be out on my ways all day. But I wanted to participate - as always I got my idea only on the verge of the deadline... so I charged my DS and drew the preliminary work on the trains (five rides on that day). It really helped, I only had to add some details and textures in PS later and had my entry! :) Thanks to COLORS! (So, nothing spectacular, but a drawing with a meaning to me!)
