On my "to buy" list for a while was the Greater Possessed model that came out quite a while ago now. I really liked the sculpt and wondered whether it would be of comparable size and detail level as the Val Gorbak from 30k Word Bearers legion.
Overall, I like the sculpt and the size of the miniature is indeed rather comparable to the Val Gorbak resin models. However, the sculpt is done in a different way and the detail is simply different to what is found on the Forge World models. I don't think this matters at all for the table top, and they would fit right in with the Word Bearers legion for any 30k game.
For my model, I wanted some red Word Bearers colours on the armour, and to have blue "flesh" coloured bits at the extremities. The images show what I came up with.
They have come out reasonably well overall, and I'm pleased with the contrast of the blues and reds -- particularly against the resin base. I think this would be a fine addition to 30k Val Gorbak squads, and I might just use it as such.
