MG Modelers Gallery is a great website for viewing the latest gunpla / model creations from hobbists from around the world (although the site is japanese, and most of the work display there are by japanese). I often visit this website because it is a great source for getting ideas for customization and paint schemes. I will be placing a link to this site in my blogroll. Visit the site HERE.
Even I had submitted a few of my work there before... =)
