Necron Cannon 3D Model

i got bored some time and decided to model the Necron Cannon from a Destroyer (Warhammer 40,000 (yes i'm sad D: ) )

anyway i thought i'd go about doing it in blender to see what i could do, don't think i did all that well though, still learning about blender but this must probably my 1st actual model of something rather than doing the usual abstract shit.
