Oi look who's there! You made me blush, man!
Anyway, great start. You have the general shape well thought out, I can see which ships might have served as inspiration. Top part could use some more love, but hey, I had ships that looked worse when I first started using them, so I won't whine about it. At first sight I had trouble trying to figure out of the top part is a huge spinal mounted gun or a kind of command deck/bridge, got it right upon entering the core but maybe it'd help visually defining it through some details. 4 stars only so I don't appear biased ;)
