I think I can give you an advice on art, not really on how to draw better, but how to create better. You see, I noticed over the years that artists look at their own art with different view than other people. We like our art, because it was made in our minds, but what if you imagine you never saw it before and never heard of it. Try to look at your art as total stranger and ask yourself: Would I want to read this thing? Would I like what I see? When you do this, it gives you a different perspective and you start to see your work in different light, many times it helps to identify what's wrong with it.
If you want to attract people, create somethign they want to be part of. For example, I created my world with mindset that it should feel welcoming The art should look nice, colorful and there are many things for people to discover. I wanted them to feel like: WOW, I would like to make a character and walk around in that world, because there is so much to explore.
Now, can you imagine doing that with your comic and art? Is there soemthing that attracts people and makes them curious? Try to think this way and remember when you became a fan of somethign that already exists, like tv show, game, comics, anything. Something made you a fan and that something keeps you there. I think this is soemthing that is very important for comic making, because it gives people reason to engage and be interested in your work. Remember, you create art not only for yourself, but also other people.
