Some WIPs

[Gors]

One tip, we WILL judge the animations no matter what, because that's what you're showing us. Animation is also extremely important and if its quality is poor, then it'll bring your work down too. But since you seem to acknowledge your poor animation skills, I won't delve on them much and instead focus on the upper sprites.

The tiles look decent imo, though some of the colors are too saturated, like those green in the grass. Also I'd say to get rid of the black outline, but it looks like you went for a SMW look on the tiles.

As for the Toad sprites, they lack the quality you find in the official sprites. The lines look wonky and ugly due to you not really understanding the concept of anti-aliasing (check for its definition in the spriting dictionary). Also, the readability in some of your frames are poor, such as victory pose and you don't seem to follow the style in the idle/hurt poses, as well as many others. I am not familiar with the style, but I think others can guide you better.
