Beautiful art !
Keeping in mind the conversion rate 1 GB : $0.50 while also at least partially considering Lioden's art community and their pricing

Headshots : Starting at 4 GB // 2$ USD per character and going up if it's a really complex design
+ 1GB // .5$ if there's complex decor
+ 2 GB // 1$ for animal decor

Fullbodies : Starting at 10 GB // 5$ USD per character and going up if it's a really complex design
+ 1-3 GB // .5-1.50$ for complex decor depending on size and how difficult it'd be
+ 1-6 GB // .5-3$ for animal decor depending on what it is

* I wouldn't charge for decor such as saber fangs or ear fluff or anything else that could simply be considered part of the character but things like bone crowns or african flower ornamants would be a totally different thing . Also you'll have to decide what qualifies something as an extra character .
Example -> If I were an artist commissioned to draw your king and you wanted the liger decor that's equipped to be drawn as well, I would definitely charge for 2 characters because it is most definitely another character since it's just as big and just as much work as the character you're actually commissioning me to draw . However, if you wanted the snake decor or the bird decor, those would be considered for the 1-6 GB // .5-3$ range because they're smaller and easier to incorperate .

It's really going to come down to what you feel is fair for your art and how much time each piece takes . You'll also need to consider if you're going to do something that's flat color or if it's shaded . Do you do backgrounds or do you leave the background transparent ???
