I decided to take one of my previous completed model and re-work on it to try out my air-brushing and weathering technique.
It seems like the more I try, the result is worst. The first picture was the completed model and the second is the re-work...
I found out that I have no control over the weathering technique and everytime I weather, I get different results and I cannot the results I want

Anyone out there face similar situation as me ?
As usual, comments and suggestions to help me improve my modelling hobby is very welcome...
