Good work. Can you please teach me how to make fire like that? 

Thank you for your feedback,

I suppose I should've added the bit of information that our games have an average dev-schedule of 2 weeks and are not exactly what they call 100% PA over here either. Of course that's no justification for not reaching for the stars, but I just feel like committing something that can be called pixel art sometimes as much as pieces that took me days and are of a more polished quality.

With this in mind: Feel free to have a go at the Proto-type. =)

The animation is cool except the front leg which stands still. Rest is, as onek put, not close to your standards.

The knee of it's left leg should straighten up along with the foot. Right leg should move atleast a little, it just looks like it's robotic joints are stretching which looks off even though it's a robot.

To take it to another level I would animate some light effects all over the sprite to maximize the effect of the gun shot.

 lots of banding. the volumes dont read well. does lokk more like plastic than metal and the colors are quite  ugly...

not even close to ur usual quality
