Awesome work. Two small "criticisms":
Although its a very small detail, the purple feels very out of place to me on the Lionheart, which is one of my favorite game weapons of all time so i might be super critical on that. (a small band of purple at the top part of the blade).
The red one (third from the top) just doesnt look right/good at all to me in general, i really prefer the original on that one (possibly due to the slight oversaturation of the red and the shape (aswell as the yellow hue) of the line in the the middle of the blade not fitting in my eye). But this is just personal taste.
But yeah overall I think this is great work and I like that you tried to make the "duplicates" in the original have a more distinct visual look.
