This model needs re-photographing against a white/coloured background as the things behind it distract from the model. The image is also out of focus and is suffering from barrel distortion. The base is a little small and the wire fence looks like it shouldn't be there - it's not convincing and needs painting properly. I suggest re-doing the base to make a little larger, think of a realistic battle scene, imagine your tank in it and take the idea from there. Sorry to pick holes 'n' all.
