Rainbows and Stars {Art Book 4} // Completed

I need your guys help with something (plz read)

I've been thinking of having a few OCs/a story I focus on more than the rest, so I can develop their story more and make things more consistent.

Obviously I'll still have my old ones and draw them occasionally.

So which universe/characters should I focus on the most??

Easthaven
Dimitri, Gesmon, Cherry, Kim, Alciel, etc.
(I have pretty much the entier plot thought out, with only a few holes and empty bits.)

Insanity Circus
RingMaster, Reality, Cyan, Smokey Nyx, Dan, etc.
(I have the starting bits planned out and a bit of the middle and end bits, but not a ton of solid stuff.)

Northton Asylum
Hatter, CeeCee & Stitches, Maniac, Lien, Rose, Dr. Fletcher, Sam, etc.
(I'm not sure i even have a single plot lol. Each character has their own intricate backstory)

Colourful Skies
Roy, Chrome, Pluto, Royal, Meredith, Juliet, Galatica, Sya, Al, etc.
(I don't have a plot yet rip)

Monster hunters idk there isn't a real name yet
Harper, Lucifer, Nise, Evee, Camryn, Loki, Alyx
(I have a general idea for the plot)

Spills and Spells
Stel, Greyson, Xavier, Arwa, a bunch of other side characters I haven't introduced yet
(I have to start planned out and several ideas for a main plot or side plots.)

Project 651.18
Bianca, Sophia-Lilac, Jazzy, Hades, Issac, Avery, Simon, & Ritchard
(I have the start and ever end planned out, with a bit of a gap in the middle)

I don't have a name for this one yet either
Minx, Milo, Neve, Tored, Vaon, a ton of other OCs I haven't introduced yet
(I have a vague idea for the plot)

Grim Reapers (This one also doesn't have a name)
That ink haired demon girl, that spooky cat I'm calling Oui, another guy I haven't even drawn out, Ari, Zakai, a bunch of side characters
(I have an idea for the plot, but nothing set in stone yet)

That one idea ive had for like 3 years
Berry, Bee, Glowstick, Showtime, Mary, possibly some other characters
(I have bits a pieces planned)

Missing Boy
Those 2 girls I introduced a while back (the red one w/glasses & the blue one with a hat) a few side characters, a spooky evil boi
(A bit of a plot worked out)

Those are my main ones, if I have other OCs u like lemme know

Here's a bunch of my other OCs I can think of that have real backstories that could be interesting

Neg
Dylan
Those yandere girls
Elias & Karl
Celine
Dolly Rose (dunno if I've introduced her?)
This poly couple I haven't drawn yet but should

I've also got ideas for fan comics? My ideas for those are
Undertale
Au where all the boss monsters that I like live together in one house on the surface w/ Frisk and Chara. A friend comes to live with them for March break and things get crazy. Might include some Deltarune characters too.

Gravity Falls
Bill comes back and he's gay for adult Dipper

K I know this was long but I really wanna know what you guys think???
