whats disgaea this is the second time its been braught up O-o
Pretty cool designs overall, love the animal onesies.
The reason Disgaea was mentioned several times in relation to your Skull Mage hoodies, is because this series of tactical RPGs for the PS2, PSP and PS3 all include a Skull mage class. In their Disgaea 3 iteration, their design looks similar to your own. It doesn't help that their classification is "Skull mage". Still pretty cool overall, but I don't know if the Gaia staff would take the risk if pissing off the Disgaea developer, though they've been known to take immense liberties with intellectual property in the past. A game changer might be that it's user-created content, only time will tell.
You should probably credit the inspiration for the Skull Mage Hoodies though. They're identical to the 'skull mage' class from D3, with the fire having been taken from Death Emizels hoody from Disgaea 4... I find it hard to believe anyone crafting something so identical on an often anime-centric forum hadn't previously encountered Disgaea before.
