I finished building and gap filling this model this morning. Below are pictures I wish I had when I was building and filling. I hope they help you. It is a great sculpt but there are several gaps. I recommend taking your time filling them – paint alone won’t cover.
Is this a new Me3 model? If so, are the new miniatures avialible to the general public?
It was available last year for a short time. I’m sure we will see it in general release soon (including via your LGS).
