Very nice
I give you a lot of credit for not just mirroring them. Thats what I would have done
On the top knight ( on the left ), the hammer looks a bit like its part of the foot. Also the mid-section does not read very well, looks like his arms are crossed or something. The towers on his helmet needs to be changed to something else I think.
On the bottom one the sword looks more like a club on the end. Needs more work to show its a blade.
