From a personal standpoint, I'd have to agree. The setup so far has been great, and I can see you doing some really fun things with the characters in the future.
Having said that, you are the one drawing this comic. It's your time, energy, and effort going into it. If you enjoy drawing this comic, then keep drawing it and have fun. But if you're not enjoying this project, then get out of it and move on to something else. No regrets.
