The portraits are catagorized by the size of the head from chin to hairline. These are quite a bit bigger than the Hometown hero portrait of Tuesday. HTH portraits are 3" and these are actually 5" so they take longer to do.
I find painting portraits in acrylic very difficult because the paint is hard to blend so I have taken to putting layer over layer until it looks right. I know there are blending mediums and slow drying mediums but since the portraits are so exposed to the elements I like to try to keep them as pure as possible in hopes they will last better. When they are finished I coat them with a sealer.
