If your goal is to create a webcomic, you have to sit down and draw it. Then when you are done, post it.
It's not like it's going to magically just happen by just doing nothing.
If you have given up (which I don't think you should), I think it might also be best to not make posts on the forums asking for advice or saying you are going to draw other people's comics. When you ask for advice, people come thinking that you might use it to make something. If you aren't going to do that, you are just wasting everyone's time and energy.
I am sorry if I come off as rude, but I feel like you have been doing these posts for over a year. If you had a full comic to read, I will sit down and read it. But after all this time you still have nothing.
