I should start doing sprites of people with Megaman animations, I'm better at that.
Here's #1 Picoman

[Adam]

Look guys! Megaman edits!

[Ragnarök]

That break the 8-bit rule!

[Chdonga]

is that bad, breaking the 8-bit rule?

[Zee]

Well it makes them not qualify for being called 8bit. And uh, these are megaman edits, and not very quality anyhow.

[Chdonga]

well, I was originally going to put these in a flash. The guy is Pico, if you didn't know. I didn't attempt to make "the best chunk of pixel that was ever invented!", It was for a contest that was cancelled and I'm too much of a pack rat to delete it or whatever. 'Sides I mostly edit sprites anyhow. So... what type of bit would this be considered as? Btw, these weren't my best ones. My better ones got deleted when my computer crashed.

[Ragnarök]

How convenient.

It's not so much that its not 8-bit, as that is a rather broad term. It is not however, NES limitations, which is clearly what you were going for with edits of an NES sprite.

Most important rule: 3 colors. No more, no less. Of course there are exceptions, Megaman being one of them. He gets by by using a separate sprite for his face using skin color instead of blue. But this cause other problems, namely the flicker fest that Megaman games were when running. And that was only 2 layers, the 8 colors in your sprite would require 3, possibly more as they aren't conveniently arranged.
More importantly it ruins the NES aesthetic you're trying to convey.

Other big issue: the actual colors used. 90% of pixel related injuries (and some 70% of fatalities) are caused by the use of MSPaint default colors, don't use them. The NES has a palette, it is required.

[Maxpphire]

Also it lacks shading. Usually 8-bit sprites have some shading.

[Zeph]

NES shading is usually pretty minimal (completely lacking in the megaman sprites he edited)

GBC era 8bit tends to have more shading and anti-aliasing and such.
