It is interesting to notice that there are so many out there that want a career in this industry. Contrary to what you may believe, if you do have talent and you do work really hard at getting better at what you do, there is a good chance that you will have the opportunity to impress. Remember that even professionals come up with something bad once in a while. The worst Marvel characters are a good example of this. Due to this fact, here is what you have to do and remember to keep improving and trying!
For starters, you can submit your work to a publisher. Make sure that you follow submission guidelines since they are really specific. Respect them and never send in something without making sure that those guidelines are respected. If you do not respect them as you believe that you are original, your application will not even be considered.
You should also consider making your very own comic book. The publishers also look for new artists on the internet. The online world made it so easy for people to publish their book on the internet. You can end up building a readership and the large publishers may end up noticing. At the same time, this is going to help you to improve since you will receive feedback from those that actually see the work that you do. It is an opportunity that has to be taken into account and it is a shame that many do not do so.
