Last night, right around the closing of the local game store, a customer came in, purchased the hammerhead and commisioned a paintjob to be done by the next evening, less than 24 hours away. That was about 7 hours worth of painting. I don't think it's too bad for being so fast.
Rating: 7 When looking at a Tau model I always expect strong highlights along the armour edges. The only drawback is that it takes a lot of time and concentration, so I understand why you didn't do this . Good job.
