@RokkuHoshiHi.
For what would most likely be allowed, please direct your attention to the original post of this OOC. It explains everything, even to the point of mentioning what we're short on so far as races are concerned. Further, take a few minutes to peruse the CS tab for examples of approved characters, past and active. There is a rich array of information available for those who choose to look.
Afterwards, fill out the CS template and post here in the OOC for GM approval. The process is long, but this increases the likelihood that you will be invested in the character and the RP. Do the homework on this. It will bear decent results.
Another idea to put out there - try stepping away from your existing character pool. Creating something original, for me anyway, is less of a hassle than trying to fit an established D&D character into the mold of the CS provided here. In the end, it's not "what the GM will allow". That is explained in great detail here in the OOC. It's a question of whether or not you're willing to do it.
