Normally this is done by others on the site (cough King cough Vision) but I'll steal their spotlight for once. Welcome to the site and I do hope you enjoy RPing with us. To answer your question it is recommended that you post your character in the WIP Character board under Character Creation, where others can read and comment on your ideas.
If further help is needed there is a
Discord site where you can ask mods directly for assistance. As you will find out if you stick around for a short duration of the time, I am pretty much online much more often, so you can ask me as well.
Further introductions, etc, blah blah. Point is, ask around! Our community is welcoming (for the most part) and will answer any queries you may have. Have fun!
