Need advice on painting my Vespids
Greetings hobby hivemind, I've finally started to take up using makeup sponges for painting and realised the immense gradient potential this hobby tool. I had the idea of painting vespids where their carapace is based on the traditional heat signature gradient, where i find myself stuck on is if i'm to paint them with the warmest tones at the highest point, or do i instead have the gradient going down to the extremities with the hands and claws being the brighest point?
Made a little photoshop demo to get the idea across roughly.
