I feel like I'm saying this a lot lately, but tell your friend to stop banding
. That's the biggest problem I see when people are trying out pixel art for the first time. Short of that their colours could use a lot of work. The issues range from things like poor constrast between shades, shading could be better defined through the use of hue shifting, and just poor colour selection in general. Point them towards some colour wheels
I'm against telling your friend to experiment with dithering because that's asking for a disaster with someone as new as they are. I always recommend learning about pixel clustering because I feel it's an invaluable pixel technique. Unfortunately, I don't have the good tutorial showing off how to do it. If someone else has that handy, a post would be great.EDIT:
Also tell them not to save as jpeg.
hey guys how do i tilt the sword?
The sword is the least of your problems right now in my opinion. The animation looks stiff and I'd go as far as to say the whole thing needs reworking. I don't understand the concept lately of moving specific pieces of the piece around and saying, "There, it's animated". What happened to drawing each frame out?EDIT2:
I think if you redid the animation frame by frame, it would likely look much better. Xion and Pietepiet are good people to question about animations if you're having trouble.
