I like the work picard has put into and may i remind people, it's his concept, if he wants to put a pink texture on it, he is allowed ;)
now may i give you some tips?

I like the basic shape! The warpengines are already better than the first ones, but if you look at it, it reminds me at a xindi reptilian ship.
Try to put these warpnacelles part in the hull perhaps, on the wings for example. Like they have sank in your wings.
