Updating Sprites on my game

I've been in the process of updating the graphics of my game for the past few weeks. My latest work, the remake of the basic enemies, I feel that it's satisfactory, what do you think?

I've already uploaded the new graphcis to the test version of the game.

The player character graphics are mostly done. Just got to give the same polish to the remaining enemies. I plan to start working on the level graphics after that.
