Very good! Love the use of the colors and the reflective light effect which makes it very shiny.



Honestly, Spike looks like he's a little bored... But who could blame him!?



Wouldn't being royalty would require him to sit in one place most of the time, partake in adventures with the mane 6 even less often and probably forbid him from helping out Twilight since he has people to do physical stuff like that for him.



I can imagine Spike enjoying his royal status at first, getting bored of it and then deciding to either step down or insist he gets to be more active like Princess Twilight.



As for his duties, he grew up as Twilight's assistant therefore it's safe to assume he's pretty good at organizing and such therefore those skills would certainly come in handy at managing the kingdom. But at the same time Spike is still a young dragon thus sometimes naive and without someone like Twilight to give him guidance he may make mistakes. Nevertheless Spike has the potential to become a great ruler but only if he put all his heart into it.
