@NarayanK - It's not to say that your characters are uninteresting. It's just that there are obvious inspirations no matter where you look. Like take for example Shiro. His weapons are ripped from Monster Hunter. His design is ripped from
************, his name comes from a favorite character of mine from No Game No Life, and his personality is a lot like Naruto's in a sense. When he's broken down like this, you can say that there's hardly any originality left.
But it's in how you as the writer/artist piece these parts together and execute them that make the character and I'd like to think Shiro is pretty interesting. It's just the nature of the beast. Over time, artists' works are going to have some similarities because we as humans go "Hey, that's pretty cool!" or "Hey, that's a good idea!" and borrow bits and pieces. So yeah, there are going to be come similar comparisons made but there are key minor differences that make it yours.
I mean, anyone can simply go "Durr hurr Call of Duty and Battlefield are the same game duuuur" but it's in the minor key differences and execution of said games that make them vastly different from one another. And make them their own unique brand, just like how Sangue and Apophis are uniquely yours.
TL;DR - SANGUE AND APOPHIS ARE COOL. DON'T FEEL BAD IF THEY LOOK LIKE OTHER CHARACTERS FROM OTHER SHIT.
