It is of very same quality when I was starting, all You have to do right now is practice, i'll recommend either cheap plastic ones in big quantitie or few metal ones so You can clean them off and start again. Keep it up.

The pic is a bit small but from what I can see the armour looks pretty good. Unfortunately i can't rate this higher since i cant make out any details. Post some bigger pics and ignore bastards like brother tiberius. That's the only way you csan improve.
