My ork army is very basic but i need to know how to make it better? i've played about 23 games and lost 1 with them

they are:
30 melee boyz
15 shootas - 2 rockets
10 nobz ( these guys are bad ass) 'ard- 5 power clawz- 2 big choopers- 3 cyborks
warbozz- mega armor - cybork
trukk- wreken ball
What should i add? and what should i give and do with it?
Thx
