Sort of, that's a complicated question.
Right now, yeah, Kota sticks out like a sore thumb. I started from scratch with his new sprites, and to futureproof them I drew him at twice the resolution with my current style, and then downsized them. That's how I'll be doing new characters going forward.
Kota looks especially out of place when he's next to Luke, Asterion and Jean because those are the earliest sprites I did for MinoH, and back then I was working with a different version of Photoshop and using really shitty brushes. Themba, whose sprites were made in April last year for example, has crisper lineart and doesn't stand out from Kota that much.
Considering it's the lineart and shading that looks most dated, I think what I'm going to do with some of the other characters is not do a complete redraw, but more of a restoration job if that makes sense? I did this with Argos for 0.5 and I'm happy with the results. Upscale the sprites, redo the lineart, touch up some stuff here and there and downscale again. Luke is a prime candidate for this (plus he has a lot of expressions I really don't like and would like a do-over), and I might redo Asterion's main sprite's lineart for example. But the game's cast is pretty big so not doing this sparingly would be a herculean effort.
Khenbish's build is coming up... I might try this out with him...
