I love the construction of the characters that you made. The form of the knights' armor is illustrated very well, I wish I could offer more criticism as to what's wrong with the piece, but maybe the poses of the knights could be less stiff, however I could be wrong and be giving a biased criticism. I more or less just wanted to express what I liked about these knight concepts and wanted your post to at least be granted some awareness. I enjoyed the designs very much.
As suggested above, helmet variations could help establish character since I would say that is the primary strength behind these concepts. There is definitely a sense of attitude ranging from character to character and this can be accentuated further with variations in helmet, tall ones having winged helms for example or the short fat one having a bulkier helmet with breathing holes. Basically shapes that help ground the overall silhouette of the character. I would also look at Dark Souls concept art to see a nice mix of real armor studies combined with unique ideas that differentiate the armor sets themselves. Adding patterns is usually what I like to do in order to add some detail, especially gold colored edges that wrap around the armor both adding detail and reinforcing the shape, it's also great for adding more color.
