Now where have I seen those Phaser designs before?!
They look a bit too small really, for the design, if they are still phasers, as the Type X strips are much larger in scale.
Looks good, but you want to try and get the pattern of the panelling and the grid lines to coordinate. I'm not fond of the corner grid lines, it's not really working. You could always try and do a very low relief modelled hull plate design stencilled on, and vertibevelled out, to build your maps out from. They should be working in tandem!
Without knowing the function, I'd say you should have some more windows, and some recessed window round the thing, and the odd few more details. Lights, transporter pads, cargo bay doors etc.
Keep up the good work!
