The new one I can tell is more like a Mii, and seems like a mpre serious character. The Current one looks more cartoony, like it'd fit in comics better.

Re: Actually it is a thing. Charmandah has had a crush on Deeno for awhile now. I was going to make a comic that pointed that out but it was scrapped (I still remember it though). Deeno isn't quite fully aware of Charmandah's feelings towards her, but she isvery good friends with Charmandah, so it'd work out.

current design is better

Stolen? I'd say it was more based on or derived from another style than stolen.

Anyway, I kinda like your current style. I'm used to it. However, the new style does look more professional.
I'd suggest toying with the new style (I mean, don't totally scrap the old style, just practice with the new one) and see if you can use it to implement some upgrades to your current style.

Anyway, I am aware of the potential connection between the different systems, but do they have the potential to compete across systems?
(In other words, can a guy playing on a WiiU have a fight with a guy playing on a 3DS? I didn't think that it worked that way and I think I am getting confuzzled.)

Jon, yes they can, but not online. Only locally.
