Oooo that was an interesting concept for Dunsparce!
Yeah, I read something about the inspo for Dunsparce being a Japanese folklore snake that was sometimes called a bee-snake and that Dunsparce was based off of that idea.
Then I kinda rolled with snake+bee all the way :)
Awesome ideas! Also, very nice art, well done! I can draw only on paper - seeing such cool stuff sure makes me want to learn to do digital some day.
I love how you hit that Pokémon style just right, balancing between elaborate and simple.
Let's see, what can I suggest fo inspiration... Perhaps a Mawile evolution (call it Mawdusa, that might be cool). Or a Tauros/Miltank baby, or perhaps try Ledian and Ariados.
Also, have you thought of making regional forms too sometime? I think you'd have a blast with that. For example, I took part in a forum event last year where we made Galarian forms for the Shroomish line - feel free to check out our fun results.
