Sorry no sketch, only letters.
I would add panel lines as suggested. It now looks like an Apache cockpit. Nice, but out of scale. I would also add some sections where there is no see though glass, thus reducing the glass surface. Further, i would flatten the top of the cockpit down, removing the current humpback shape and replacing it with a classic ww2 German greenhouse look that sticks up from the hull, but not as much and hugs its general shape better. Adding fine Grimdark wires, vents and hatches of a minute scale will also help out a lot.
Lastly, I think the tail is a good start, but I find it way too small. You need two huge fins V-wings/fins that are also attached directly to the aircraft, not to a vertical tail. That looks off on your much more exciting curvy design.
I hope this d not sound like I am overly critical. I do think you are on to something truly wonderful here. But sense of scale is very important.
Edit: oh, and why bother about looking exactly like the picture? It does not work anyway and I am sure you have changed a few bits already. I think the changes suggested, or others to the same effect, will improve a clearly underdeveloped concept found in that picture.,it will still look similar to it, but it will have your distinct (nicer) design elements added. That is creativity at its best in my book. Keep up the very good work!
