It... Is... A... SKULL!!!
Yeah, srry about all that. I am SUPER DUPER new to all of this so I didn't know what to do. Now I think I have the general jist of it though. Thx for the tips cause they REALLY helped me out for the pieces I did after this.
we have a zoom feature built in. also, those greys could be used more efficiently to reduce jaggies. where they are used, they seem to be creating banding. you may also want to increase the canvas size so that the image elements (namely the eyes) aren't touching the borders of the image.
It appears you must have saved this as a jpeg image instead of a png or a gif, as it currently has 251 colors. I'm sure you didn't do it on purpose, but just as a reminder: NEVER save pixel art as a jpeg; it ruins the picture.
