I am very new to pixel art. Though I have messed around with it before (nothing impressive), I would like to learn as much as possible before jumping in. What are some of the most recommended things to start practicing, for anyone just beginning? Or should I just go for it and let experience and critique be my only lessons? I understand that there are tutorials out there, but I see those more as a tool (doesn't help much if I don't know what I'm really doing in the first place). Any advice would be appreciated.
