as the previous poster put, folks buy art, not doodles
hell banksy couldnt sell pics in newyork for $60 a couple of months ago.. go figure
I think people may start to buy your pictures only after you build your authority as an artist and you need to get some fans first. You can try to give away some your arts for free or expose them on some websites where art lovers may notice them. Besides there are websites that specialize on selling arts where artists may register and sell their works. I think such website may be a better place for your works than ebay.
But first you should think how to improve the presentation of your arts. I agree with previous answers, nobody will buy a picture on an A4 paper. People can simply print any nice picture instead of buying yours. So, you need come up with something to make your pictures look more professional and complete.
Think about it, no offence but most people by pictures to hang on their wall and decorate their house, not many people are going to hang up an A4 people of paper that somebody has doodled on?
