This plate armor knight came in a learn to paint kit from Reaper. Total paint time was somewhere in the 6-8 hour range.
Here is a picture of the unpainted model from the Reaper website. This model is from their Bones series of miniatures which are ready for painting.
Reaper has a few photos of different color schemes, but I followed the instructions in the box, which dictated a silvery-metal armor and blue accents.
Here are a few up-close details using a macro-lens attachment for my phone.
