Here is what I came up with for the sketch, kind of a balcony point of view. I'm going to start coloring it today.....
Didn't know where to put the lion crest, since you didn't mention shield. Didn't want to put in front of tunic, since the straps of backpack (which I will add when I color) would cover it up. So I used it as sort of a buckle, hope thats ok? Remember this is a rough draft, I'll add a bit more detail when I color. If you want any changes made, shouldn't be to hard to fix, since I will have it on layers, just lemme know.
