1 - Find a native speaker of English that don't know how to draw, but wants to create comics anyway.
(You're an artist, and that alone is super valuable, there's lots of writers out there that can't draw very well)
2 - Find a proofreader, and either pay them with drawings, or pay them with actual money, some even do it for free as long as you credit them.
3 - Learn the f.ck out of English grammar, vocabulary, idioms and specially phrasal verbs, that sh1t is usually hard for "us" non-native speakers of English bcuz our first language's rules get in the way.
NEVER GIVE UP!
GOOD LUCK!
