thanks, i'll make sure to read those when i have the time.

and, oh right, i should of noticed that looked strange, i'll keep that in mind and try to improve with my future work.

In my opinion it's good especially for practice to use only a few colors and I don't advice you to randomly throw colors in but to thoughtfully decide what colors to replace the outline with (and expirement and play around with it!). That would end in 3~5 colors more I'm estimating. It's not a biggy and I would advice more to try that on the piece you work next on instead of "fixing" this as it's not really a mistake.

This tutorial has a small section of banding in it. I however only really grasped (at least I think ) banding after reading Helms Ramblethread (way longer but a good read as long as you keep in mind it's a ramble). Over a month ago, I tryed to explain it in my own words as this:

Banding is bad because it creates strong, secondary forms (you interpret these pixels as belonging to each other because they line up) that stand out in a way that they break the actual form of the subject in the image and disrupt the flow of the eye. There're cases where it's more strong and apparent and cases where it's more subtle. It's comparable with when spaces line up between multiple rows of text and create a vertical "line" which disrupts the horizontal reading and increases the chance to loose the row greatly.

I've made this quick zoomed in capture of your picture to show what I mean. The blue line represents roughly how the form is percieved ignoring banding. The red blinking box shows for me the strongest banding on that part and due to the square nature creates this big, square, clutzy thing that disrupts the form. But again, instead of fixing it I would try to be more "on the watch" for banding in your next piece. And don't go crazy over it either, I know I did after hearing about it the first time. Now I think a bit of banding is not a deal breaker as long as most prominent cases are avoided but find out for your own.

for some reason i thought that i shouldn't use that many colors, so i didn't do that...

sorry, but i'm not familiar with banding, can you point out the parts that had it?

and yeah, it made perfect sense, thanks.

Welcome!

"im not sure if i'm even good enough to be on this site, so please give me feedback."
Don't worry too much about not being "good enough". I'm not a spokesperson from this site but afaik submissions are more judged on about if it's pixel art or not.

For me personally it's hard to give feedback on this piece but I suggest you to try dark, colored outlines instead of black ones (at least in the in-between parts). Black seperates the parts of the piece quite extremely and while that surely can be used in a positive way, I think it's too extreme in this one. Overall your piece works good, imo. There're some banding pixels that could have been avoided but nothing to go crazy over.

Hope that helped or at least made sense
