So, i been looking at your art recently and i just wanna know, is my art good or back? I try my best but to me, it's looks rusty compared to some of my old drawings....

I don't think your art is bad at all. You have a pretty good grasp of the style and how to apply color, actually! What I think is going on here (just based on these two pictures) is that you might be struggling with making your own lineart from scratch, and it's giving you the false impression that you've gotten worse. In reality, you've just graduated from tracing, which is awesome (even if it is disheartening right now)! If you're worried about your lines not looking as good as official art, you could keep a picture of Gingerbrave (or whatever cookie has the most similar body type/neck style to the cookie you want to design) on the same canvas as whatever you're making so you reference where things go and how the characters are typically posed. Oh, and don't forget to flip your canvas horizontally sometimes so you can see how it feels when it's facing the other way. If it looks weird when it's flipped, fixing it even a little will make the unflipped version look a lot better.
