This is clearly a Grey Knights Dreadknight replacment. I like the idea of making it look like a scaled up marine armor. To be perfectly honest, I'm not a big fan of the "baby carrier" style of the official Dreadknight.
A friend said he thought this model was too "busy", but I think it has a lot to do with the paint job. If you put thay much non-metallic metallics on one model and paint it predominantly gold, it's gonna look busy.
