ROBOT ENEMY SPRITES THAT FIT WELL WITH RM2K3 RTP

I am looking for a few enemy sprites of steampunk-ish style robots/machines that would look fairly good with the RM2k3 RTP side-view battle sprites. I have checked a few websites, but so far I've been unable to find something that I liked.

If somebody could provide a link, or even make/rip something just for me, I would be eternally grateful. :)
