Didn't have anything too specific in mind. Armour is basically early 15th century. Around the time of Henry IV. The arms of Joinville of Champagne (with the red lion) and Beauchamp of Warwick (red with yellow crosses) feature .
This is amazing, better than I could do by a longshot. However I cannot help but feel as if something is a little bit off perspectivewise. It could be thickness the dividing barrier and it's wooden planking. I would also put a little more contrast between the defeated knight's clothing and his horse's. but i love it it's fantastic ^^
