1/100 MG Gouf Custom WIP 4

Hey guys, new update here in regards to my Gouf Custom. I was out of town last week and then i had finals this week so I didn't have much time to work on it. But finally I had some time today (on mothers day lol) to finish my gouf customs Gatling shield. I did some chipping and rust streaks but I don't know how well they came out. I think my sponges pores were too big, may have to sue as smaller sponge. Well, let me know what you guys think and any tips n tricks you think I should know. Well till next time~
