That's a tough question to answer without sounding pretentious or cheesy. I'd say I did a really good job writing the action scenes, and I think I've made some characters people would find enjoyable.
I shall offer my services. My only reference is a five year old who told me my stick figure art is "bad". If you are interested in seeing my art, I have none. I am willing to negotiate my fee, but the standard is three thousand dollars. Please reach out if you are interested in terrible art.
