Wow. That was a ton more information/detail than I was expecting. Thank you, anon. Let me see if I can compensate you just a little.https://twitter.com/hsa16g
Has a cute artstyle and also retweets a lot of stuff. Nino!https://twitter.com/ch_i_ba
Hasn't been around long, but their art is cute and a bit lewd.https://twitter.com/s_a_t_o__krkr
Only noticed this guy today, likes FE6. Seems to have a Pixiv, though.https://twitter.com/yukiharu33
This one retweets art, mostly, but does draw on occasion.https://twitter.com/whppw062
Mostly retweets also, but has drawn a lot of Serra and Erk
pictures too. If you hadn't guessed, Serra is the common thread between these accounts.https://twitter.com/firstaid0/
That one guy who does all the Julia pictures. Luckily, he uploads his stuff on Pixiv, but better safe than sorry, y'know?
Thank you again for all the information. Have a rare Serra from an account that I chose to omit because they've drawn little and don't seem like they'll be doing more any time soon. nekozirusan, if you're interested.
Someone really ought to create an account that aggregates as much FE twitter art as possible.
