OC Sprite character animations

[Bombshell93]

many problems but I'll start with the obvious, you saved your image as a JPG (for those unaware DA does not change the file format)
this leads to artefacts which distort the image beyond its intended look.
Next is the fact these would not likely be used as or even considered sprites, the seem to be drawn but sprites are rarely ever drawn because the sometimes subtle sometimes jarring human error in things like line art and colouring could and often do lead to graphics lacking in the crispness expected of games,
What is usually used instead is vector graphics built on top of the drawing.
Then there is the size, these "sprites" are MASSIVE a game using them would never fit enough on screen to make a playable game unless a large resolution were mandatory.
Moving on the anatomy is fairly odd and it looks like the character is some kind of jelly man, not to mention the feet art stubby and fat, the shoulders are balloons and the head is ambiguous between a blob fused with a white jelly been and a golden hedgehog.
Finally the shading is blurred not helped by the blurry line art which may or may not be a product of the JPG compression.

My advise is pick between these 3 mediums,
PreRendered graphics (3D models rendered into 2D sprite sheet),
Vector graphics (recommended for drawn graphics, but they do come with a challenging skill set of their own)
Pixel art (quite often drawn graphics are turned into pixel art for key points in a sprite sheet, just remember to scale down your image to pixel art over it in a comfortable size 64x64 is a good all rounder)

Then do research into whichever medium you choose and practice and practice and practice, for Pre-Rendered and Vector there are likely better forums to go to for help, but if you pick pixel art its out specialty here
