Forest-Fighter: Home of the Arsenal

[Sevenstitch]

The main way you can clean these guns up is by reducing or removing the amount of dithering on them; on sprites this small dithering tends to just jumble
up the image. Also, perhaps you could limit the highlight tones on the guns, as many of them have single or double pixels of highlights in strange areas that
break up the lines of the guns.

Try reducing them to the primary shapes of the guns the sprites are referenced from and only add detail where necessary instead of everywhere the reference
has detail. At sizes this small readability in the sprite is more important than overall accuracy to your reference material.
