Alright, ended doing this on the four-hour coach journey back from Bletchley Park. It is, essentially, art of what I would imagine to be on a Bull Golem sprue. Much easier than drawing it all together.
Alternatively, you can imagine it to be the very obscure blueprints sent out to Dawi Zharr Arcane Engineers.
And then I messed around with it a bunch of times!

^My personal favourite.
Wow thats cool i like the last one too it look like a blue print of the bull golem
I think the pilot would look a lot better if he were standing up. A little like Ripley in Aliens.
The knees and elbows don't quite feel right. Maybe they need either some optional armour, or something to protect the joins?

I agree.

I was thinking of adding some scalemail and/or leather drapey-things as optional addons, along with some pauldrony-things for the joints.
That is a great design I top my hat to you

Do you plan on building it or will it stay a drawing.

Covering the legs in chainmail/scalemale would look good. Maybe add a few skulls on chains?
I completely love this copcept design! I urge you to try and make one of these puppies. Hats off my friend!

Hey, pretty sweet! Now to construct it!
Is there any background for a "Bull Golem" official or otherwise?
I guess it is meant to be a Kollossus
Or it's meant to be a Bull Golem. 
Well lets see you build it.Pluss he need a cup holder.
All-mighty cup-holder of HASHUT!!! I love it, add it now please.
