One more pic, my entry for the GFX compo at Breakpoint 2006, created at the party. I was really tired when I was supposed to create a background just before the deadline, so it didn't turn out very exciting

New pic, with photo reference though, so it's kind of lame. I included the steps because I thought it's kind of funny how it starts out with this crappy drawing ^^

I use MS-Paint by for pixel-art is good and for make the graphics pixel-at-pixel you not need more...

Well, you don't even have keyboard shortcuts or a proper way to manipulate the palette in Paint, nor a usable cursor. While it is entirely possible to work without these features, it's really not very convenient. You should definetly take a look over your horizon and try different tools ...

But after view all the demoscenes considered pixel-art, i think not all is made pixel-at-pixel and use tricks or short-cuts for make dithering, forms, AA, reflections, etc...

I talk with another amiga pixel-artist, and he said me with deluxe-paint is more easy make pixel-art that with other program (this is their opinion) have the perfect tools to make this, anti-alias, dithering etc... and for demoscene logos not all is make pixet-by-pixel. He make first the line-art and create the bevel. After get a texture decrease colors and retouch the pixels for their line-art and put the anti-alias automatic using the colors(all in grey scale) and for finish change the palete, create details pixel-at-pixel for all the draw etc... and have the demoscene logo.

Now, with this steps i have an idea that how can make the incredibles demoscene logos in pixel-art.

You said all the demoscene logos can made in Ms-Paint(just take longer). I view this, and think he not use Ms-paint jejeje, and think for make this in Ms-Paint is imposible. If you get the image and zoom view imperceptible colors or soften on this. I not think this image its made pixel-at-pixel.

Believe me, it's possible in Paint - I mainly use Photoshop for pixeling, but I don't use the features which might be considered as "cheating" when creating pixel art. Fullscreen graphics like the one you gave as an example are a little different from scene logos though imo, they're way more complex.

I view more demoscene logos and all the artists in gfxzone etc.. have a logo... but i looking for a "demoscene tutorial logo" and i not find nothing. I view tutorials of pixel-art that all types... by why no anybody made a demoscene tutorial logo of pixel-art? I think will be interesting...

There's a tutorial right there on GFXZone - http://www.gfxzone.org/articles/goblin_pixelling_tutorial-article.html

It means Color Graphics Adapter, see http://en.wikipedia.org/wiki/Cga for more info.
