If you were supposed to get an email from the forum but didn't (e.g. to verify your account for registration), email Wes at stararmy@gmail.com or talk to me on Discord for help. Sometimes the server hits our limit of emails we can send per hour.
A few things I'd point out. When you said you made that picture in a certain program...did you like 3D sculpt it all yourself? Or pick options in a character creator thing? Or like make her in Black Desert Online or something? Because they usually want you to only use images you own the copyright on. If you made it with a creator you generally have to credit/link back to it (I think). Also you want to embed the image instead of linking it.
It's hard to get into RP without being part of a plot, generally. You can go through Open RP but it's usually a better idea to slide into a plot. Again, @Jack Pine is a good choice to start with, or @Alex Hart and @Zack or @Legix might have ideas for the flavor you're working with.
Small note, there's a mech/armor called Reaper already, so might want to add an extra word or otherwise adjust the name to make it easier to tell apart. Also that's a lot of NPCs to start out with. It sounds like the whole cast of one of Jack's plots, so it might be easier to slide into ISS Brimstone or something similar rather than running all those characters yourself.
Don't forget to create your user page! The little red link up at the top. You can just throw some basic info on it, like when you joined, what type of RP you're looking for, Discord information, etc. At the very least, it's a good place to list all of your characters.
Jarth, if you need an example of a basic player page, mine is a good place to start in terms of simple information (At least I hope it is) that take about five or so minutes to fill in. Just list some basic info and your characters! Nothing too fancy, unless you enjoy Wiki Work or ensuring everything is above standards, in which case I doubt anyone would oppose it!
