Here's a picture where I was experimenting with fiery effects using the paints on Art Academy.

Yeah, I'm still pleased with how this looks. I'm not too confident when it comes to stuff like this, but you just gotta take the chance sometimes.

The Marowak pictured is a design concept I dreamed up during the build up to Pokémon Sun and Moon. We didn't know Alolan Marowak was a thing back then and with the whole Hawaii themed region, I thought it'd be pretty sweet if there was some kind of Marowak based on the kind of fire dancing that country is well known for.

I was sorta right, although I doubt I was the only one who thought of that particular idea.

Since then I've made that Marowak design an actual character of mine called Jasper. He's currently the subject of a fanfic I'm writing up, but that's not ready yet.
With that said, the design in this picture is a bit out of date, I've tweaked some aspects of him since then.
