1. I could create another account in which I post sketches. It should be noted that my sketches are pretty rough (for an example, I left Guro in sketch form in this picture). I can generally get a sketch done very quickly, so I would be able to post to the second account often, and it shouldn't interfere with the comic or any other projects on my main account.

2. I start a mini-series in which you could ask my OCs questions. I'm a little hesitant to do this one, as I know that other users have done something like this as well. As far as I know, no one claims ownership of the idea, but if there are any objections, I would like to know. I just thought it would be a neat way for you all to see what the characters are like. These would probably have characters portrayed in full color with no background. These will probably be finished quickly as there will be little focus on perspective and I wouldn't need to worry about backgrounds.

Anyway, I would like to receive feedback on these ideas. I may end up implementing one of them or both of them depending on the feedback I get. If you have other ideas as to what I could do, then you could share them here as well. Thanks for your consideration!

I think the first option is better.
My reason to chose that one is because I believe it's more fun and easy to do sketches of what you want, not to mention I kinda like good sketches once in a while and your sketches look clean. That makes it easy to understand (unlike mine XD).

The second option is great too, but I don't know if you'll feel burdened after a while with all of those. Sketc.hing has freedom XD.

... Why is sketc.hing censored º-º?

Both ideas are very nice, both with their own ups and downs.

Perhaps a sketch account will be better, as you don't need to depend entirely on input from others and you can post what you like whenever.
