I very often try to argue that concept art and other artworks are a great source of inspiration. They are not only beautiful to look at but can be used to achieve very cool results in scale modelling. If we look at the the atmosphere, colour temperature and lightning, we see that the combination creates very interesting pictures. If we apply the same philosophy as a whole to our scale models we can achieve the same effect.
We can also take this much further if we choose to create a base for our models. With a more artistic approach and following visual key elements of concept art we can capture a more dramatic and interesting atmosphere on the base to.
Google is your friend when looking for inspiration. I especially find concept art for games very compelling. To show you what I mean I have added some very cool pictures here.
