what sort of classes would you put with each character

Bowser: Sentinel
Mario: Rogue/Scout
Luigi: White mage/Priest
Yoshi: Ranger
Toad: Monk/Boxer
Peach: Knight/Warrior
Rosalina: Sorcerer

That's glorious

Bowser knows what to prioritize with protection xD
This looks great <3 I'd totally play a game like that (Because Mario RPGs are always fantastic anyways)

Guarding the goods. ;D

this should become the next Mario RPG game installment after they do that durpy looking Mario and Luigi RPG + Paper Mario crossover. XD

Absolutely fantastic!
LOVE the energy in the poses, such a nice composition, great work with the negative space

Thank you very much!! Really glad you like all the little things. <3

Wow, lovely wallpaper dude.

Thanks man!

Your welcome. :)

Great Job, cool designs.
But it hurts my brain to see them in different classes than my head cannon.

And what's your head canon?

Bowser: Strong -> Defender/Barbarian/Tank (Spot on)

Mario: Versatile/Controlled -> Warrior/Spellsword

Luigi: Quick & Agile -> Rouge (High DPS)
(Usually seen as harder to control than mario, with lower strength but higher speed, especially in Galaxy. The mansion games can be seen as an opposition to this, but he doesn't have the regular mario jump in that game either. Plus he might act that way because he was so scared.)

Yoshi: Flutter jump + egg toss -> Ranger (Spot on)

Toad: Not much on him actually -> Monk totally works, but so might other things.

Peach: Association with girly things, peaches, and pink, but also powerful in the sports games -> Healer w/powerful attacks but short range and low defence

Rosalina: Magical -> Caster (However, I always restrict her to pure 'astronomy' based powers in my headcanon, so no fireballs, and such.)
