Okay the Tattoos scream Forgotten Realms, the summoning spells scream FR, Planescape and MtG. I like the Tattoos, they are fine.
The summoning spells need some tweeks.
Along with type, you should be able to choose size, small, medium, large.
Not all clerics are good, so either clerics should get Summon Fiend as well or Summon Celestial Should get a Fallen option.
Summon Celestial should be dropped to a lower level.
Why is there still no option for summoning Succubi? They should add Succubi option to Summon Fiend or make Summon Succubi an option for evil or dark Clerics.
None of these spells displace the value of any existing spells. Summon Fiend is hirer level then Summon Demon or Summon Lesser Demons, and even Infernal Calling. Still honestly Summon Fiend would be worse then these spell except for 1 key thing, its safer! None Evil Fiend summoners are better off with this spell and its tame fiend.
Summon Celestial is no where as good as Conjure Celestial, so its only real advantage is its lower level, which should be even lower. And its options need better fluff, compared to all the other Summon Spells, its lacking flavour. I suggest Archon, Angel, Asuras, and Fallen options replace the current ones.
I really like Summon Fey, Summon Beast, Summon Undead, mostly as is, but add a Vampire option to Summon Undead, and as I said let the caster choose the size (small, medium, large).
Summon Aberrant is really cool, but they should add a Flumph option.
