No problem. It's not that the flashing effect isn't allowed, It's just the way you brightened the pixels to achieve it. Most people around here would expect you to either use colors from your existing palette or add a couple more colors instead of just brightening them. It's kind of strict, but that's just the way it is. Personally I though the effect was fine the way it was. Anyway, your pixel art is looking pretty great so far. Keep it up!
Welp, i'm pretty new to PJ so i didn't know that flashing effect can be considered as non-pixel art. Thanks for a good advise. I fixed it now.
This will probably get accepted when you fix the flashing effect. I'm pretty sure it's considered NPA. This looks pretty nice otherwise though. I like your characters.
I like designs of these characters :D Very nice-looking pixel arts ^^
