UPDATE 9/22: Cure wave has been cleaned and finished.
I've said it before and I'll say it again: I'm loving the International PreCures in Happiness Charge! It reminds me of the old "world tour" arc from Digimon Adventure 02
It's such a fun concept that I just couldn't resist drawing these two since they took the time to flesh them out a bit more and give them their own proper transformation sequence, but I also find it funny that they're also kind of Tropical Rouge Pretty Cure before there was Tropical Rouge. I also intended this to be a bit of a farewell to Summer even though it ended up getting pushed back a few weeks.
As for the sketch, you can see I ended up running out of time before I could clean Cure Wave, which is part of the reason this got pushed back the way it did. I was a little too ambitious again and didn't learn my lesson the first time when I tried drawing Cure Bloom and Cure Egret together, but it might be fore the best this way since now I can still potentially play with the positioning a bit if I want to... other than that, Sunset's..... right hand (uh... the one that's at an angle) had to be traced in along with the big flower in her hair because I wasn't happy with how my attempts turned out as well as a bit of the end of her hair to fill in what got cropped off... lesson learned: from now on when I try to do something like this I'm doing each character in full individually and putting them together later...
Pretty Cure and all relate characters, including Cure Sunset and Cure Wave, belong to Toei and any/all other respective owners. I don't own the character(s) in any way, shape or form, I'm just a fan!
