Since I forgot to give you proper feedback before I'll go ahead and do it now.
You need more to your RP's, more detail, more dialog, more description, more everything. While length really doesn't matter, it does when an RP is so short that it doesn't get much accomplished. You're basically cutting promos, not writing RP's. Take a look at what everybody else does and kinda go on that by giving us some story and some match talk.
If you have any questions feel free to ask me or anybody else on creative.
