Howdy Gaz,
The model looks great to me. Will you be hitting it with a coat of "dullcote" to knock the little bit of shine off the turret? That is the only suggestion I have to give you on the model.
As for photography, once you finish the model, try taking it outside and sitting it in a bare spot in your yard, or on your driveway. Then take your camera and sit it on the ground, level with the model and snap a picture. Ground level shots in a realistic looking surrounding are one of my favorite ways to "shoot" my models. Have a look at some of my models in my gallery to see what I mean about "ground level shooting".
The human eye is not used to seeing models from that angle and therefore, even if you make a bad picture, it turns out pretty good because the angle is different than you would normally see.
I hope this helps, again, the model looks great.
Have a good day,
Greg
heres one of mine from ground level:
Oh, one more thing, the wire from the "tie twist" used on bread wrappers make great antenna once the paper is removed.
