I like the...steampunk...kinda feeling i get from the robot and I really like the glowing sword and magic
what's interesting is, that the red glow sort of makes the knight look like the evil one on second glance
at first it's all like: "the robot is holding the princess prisoner and that knight is gonna save her"
but when you think about it, it might as well be ht other way 'round.
for example: the princess could have run away from home with that robot, the knight as sent to bring her back just wants to protect her from that
sorry those are just thoughts
so long story short: this is a really nice work and a well deserved DD
