for a first timer, it's ok.

on my personal observation from years of rendering services... one should always bear in mind, that it's not proper to ask for too much until he/she gets to prove one's personal worth.

if a company has reasonable management in it, the proper compensation comes later to those who deserved it.

if its dificult for a management to see ones' value, there's always a chance to step out and look for another...

good luck and all the best ;)
