there seems to be some problem with pixel proportions in the second image
overall it's pretty basic and a decent sword, however
the black outline on the sword itself doesn't serve to help the shape, but rather makes it look off, dont use it, but this might be a style preference, maybe it would look more appropriate with a dark outline on the hilt also
the purple jewel is not very visible at 1x, you probably need stronger contrasting colors between the jewel and the hilt and the hilt's shadowy parts
