Hi! I'm here to critique this, so here I go...
I really like the vision, it's subtle and clear, but the lines are out of shape. (The leaves are rounded more.) Although, that barely effects it, I suggest trying to use the curve tool more often.
This is a very unique image. Not many people consider animating in this style, and of a creature (although simple) needs all parts just right so you know what it is.
Yes, the technique is very seeable. I agree with a simple technique as this to help make animations like this, but it would be better with a faster speed (maybe 0.5 faster?)
I'm unsure of impact, but if you mean the feelings of this picture, I'd say it is very nice. It actually adds to my liking of your art.
Altogether, this art is VERY enjoyable. I also like your type of style to the shading, as it remind me of some very nostalgic games.
Are the people who think "FAIR" with the critique or the art?
Depends. Fair, determines the thought if you think the critique was good and suitable. Or, you can think it fair if you like the art, but mostly on the critique.
Thank you for the critique
Unfortunately, the animation can't go any faster; I already set it to the fastest loop speed.
Other than that, it was all very useful
