At normal tabletop distances there isn't any. At 1 foot still none. At 3-6 inches there are little things, extra shadows and weaker highlights but nothing that would make them as bad. More like painting when tired or like the tenth fig in a row. Overall I am going to call my dipping test a success. This means I need to get those other troops assembled and with any luck the main force will be done in the next month or two. Now I need to find a way to speed up painting the white pieces of my army. I have 3 or 4 more Devilfish, 6 more piranha and a at least a dozen battlesuits. Looks like I am going to have to get to experimenting.
