You did well on the Animation! :D

Its a very good attempt. Very stuttery though but it takes time to get in to the groove. Good job.

What's she welding? 👀

I saw the thumbnail, and immediately knew I was gonna see some gold. Gotta say, happy to be correct.

The character design fits very well with the art style, and I love the attitude you gave her, its a very nice mix of calm yet cool, without showing any sense of apathy.
Your work on the lighting is very impressive as well. Its very cool to see the light flash rapidly as she is welding, it helps give a sense of intensity that I really like, while not being overwhelming or conflicting with her personality.
You also have very good keyframes, the posing combined with the timing convey her actions very well, and really show what her personality is about. You have a very good grasp on how to convey a character through animation.
If this is an animation test, I can understand the lack of inbetweens, but adding a few more inbetweens here in there could really make this even better.
Lastly, this would benefit greatly from sound effects. She is listening to music, so it would add to her character even more if we heard the music she was listening to, whilst hearing the welding as well.

Outside of that, top notch animation! I really do believe you should continue 2d animation, you've got good talent and a great grasp on key posing and timing, two very essential things.
