Okay this is my first Pixel art,so I need feedback .There's 19 colors,there's almost no AA cause i'm too sure how apply them.

Also i'm not sure if something is jaggies or not, if something looks off i'll try to fix it.But my eyes are still untrained so if there's jaggies(or banding etc) please point out what I did wrong.

It's fine without AA I think.

The white jism bits feel jaggy. If they're not meant to be jism, they should taper off and not be so curvy, and probably be thicker in the corners (but not intersections).

The hair feels unfinished. It's too regular, doesn't feel like hair.

Necks do not get wider the lower down they go. If anything, they get narrower. There are muscles on the back that can make them look wider, but that widening looks very different from how you drew it.

The controller and hands read as being a controller and hands, but they don't really look good. I think more indication of buttons on the controller would help. The hands have multiple issues, to the point where I don't know what advice to give because I don't know what you want to do with them. If you want them to be holding the controller in a neutral position, then they should be more foreshortened. If they're meant to be seen from the side, then more of the back of the hand should be visible.

I don't think you need the corner around the logo, it adds jaggedness but no design benefit.

Lastly, as a logo, I think it has major ssues:
- The text is tiny and not immediately readable. The text is legible, but because it's small, it takes deliberate effort to read it. If you want people to remember your entity's name, it should be more prominent.
- The visuals are complicated. That makes the logo hard to reproduce. Most logos are kept fairly simple so that they can be reproduced wherever they're needed, even if it's with fewer ink colours. If you just want something to put on your site and this isn't for branding your products and reproduction isn't an issue, then you don't need to worry about this.
- However, complicated visuals are hard to remember and associate with an entity. What is the point of having a logo if it's not helping people remember the thing the logo is for? A logo CAN be complicated and still be memorable, however in that case it needs to have something very memorable in it. For example, the Starbucks logo is memorable for its subject (exhibitionist mermaid) and specifically for its complexity of white and green. Some full-colour logos are memorable for their characters, or for the action depicted. In your logo, there's nothing that interesting - the visual is something seen in a lot of video game-related material, and the colours are not memorable either. Eye-rolling video-gaming orgasm (if the white bits are jism and not lightning) could be something unique and memorable, but your logo doesn't push that visual, it doesn't burn it into viewers' eyes.

Sorry about that Jalonso ,I guess I just saw all of the other thread got replys,next time i'll wait longer

@eishiya umm,thats not jism(I see people why might think that) that's electricity lol,i'll try to fix it.
The neck well...,yeah i know I still have a lot to learn,i'm still not that good with anatomy.

The hand and controller,I imagine the guy getting shock(not orgasm lol) so whatever position that hand might be in a
shocking state I guess ...,but I'll try to improve upon it(more buttons coming up).

About branding,this is just meant to be a logo for my games.I'm not
too concern about branding at the moment but appreciate the advise.

But other than for branding purposes,are the colors good enough?,any way I might be able to improve them.
