So i had this laying around in the garage and realized it seems to be perfectly scaled for
40k and its actually quite nicely detailed. So i'm thinking of a bit of a different paint job, possibly red/bloody horns, or even maybe mount a
CSM on top of it?, i will use green stuff to get rid of those gaps between legs etc, and i would remove the inside winding part and cut the winder off. But i am hoping i can get some ideas from you guys which will help me think what to do with it

. Maybe chains drooping off the horns?, or should i try and create some sort of chaos armor to cover most of its body?.
By the way quick off topic question, is it a "legal" conversion i made with that marine by giving him the tanks flame thrower instead of the regular
CSM one?
EDIT - I think this could be a
Mc Donalds Toy from the 90's
