One thing I could throw into the bin if you're looking about the RP: look at other CSs and try to make yours the same length they are... One thing I am noticing in the CS is a lack of detail. 

If you are interested in taking them and will down the road take another shot here here's what I can give:

Why not explain his training? What did he learn? 

What was his first encounter like when he returned to the society he once knew?

Why is he trying to find answers?

Ya know.. Some easy stuff that sounds crappy when separated and brief, but when you put them together: bam you made a bio for Zeal.

Look at the other two CSs for reference!
