I would totally be down to draw most of those OCs! (especially Hemera, she looks adorable)
My commission info can be found here and here
more art examples can be found on my twitter and in my FA gallery
the only critique i have is that your colours are very saturated. you should try using different hues for shadows or lighting. warm lighting with a hint of cool shadows, or vice-versa, always makes for a good combo and can make a huge but subtle difference. other than that, looks great!
