I could give a few other decent ideas, maybe make some sprite sheet examples, I need something to learn the start of animation in blender anyway. I know a bit of modeling to slap on something of a "jetpack" of whatever style, or the base idea you could do in your blender setup is just have her flap her arms and the tail wag exaggerated/a bit faster and bobbing, or go full cartoon and propeller or semi propeller it.

Not as of right now, as I don't have the DLC (Shame on me)
I also want to still try and fix the shadows, I've not been able to look into that as of yet, especially now with the end of the year getting closer, but I'll try my best.

I had some ideas for the mech suit already, which would be the big mascot suit that she had posted pics about every now and then, to keep it with being a "big and bulky" design, but that might change when I see the actual mech suit in-game myself.

Though I appreciate the offer and you're free to use the code from the gitlab and make your own version, I won't stop you!
