Croak's Creek : the Wasteland's residents

Here are the residents of the Wastelands, an hostile environment fillend with lifeless mudd in my game Croak's Creek.
Out of all the inhabitants of Croak's Creek, these two fellows are the weirdest, but don't worry, they're not evil.
I first drew them on Photoshop then I pixellised and edited them on Piskel to finally integrate them in the Unity project.
