hey hello, welcome to colors! i'll be your awkward assistant in learning stuff xp
if you want people to see your art of specific characters, like springtrap here, you'd add something called a #tag to your post. adding it to the top is more recommended, since if it's at the bottom, it might glitch the playback's playbutton so it's hard to, well, play the playback
you would add #springtrap or #fnaf to this, and it'd show up,in the related drawings, but, tags cant have spaces or anything other than letters or numbers. for example: #five nights at freddys
it defaults to just #five
tags also cant be super long, like #thistagiswaywaywaytoolongwhatabigoof

also, with how replying and commenting works on here, you'll never get any notifications for any type of comment, so if someone comments on your post, go to their profile and reply on their latest picture, preferrably with a "re:", "re//", etc. at the front so its known that you're replying

i hope i wasn't too confusing, if i was, sorry-
