That is a very cool model, thank you for bringing it to my attention.
It reminds me of a coelacanth and would look very fitting with blue skin and Tau armour added on. Add a few antennas and presto, you have an ally. If you could pose your model next to a scale/ruler or a different GW model of equal size then that would help. You could easily use this fellow as a stand in for an ally.
How about getting back to that member profile Blueshock

devote time and effort into helping you so maybe taking a second look at our site guidelines would be best?
