Quoting qwerty 10
I find it difficult to make something on LDD from scratch, but you seem to do amazingly well. I would only suggest to tilt the cockpit like Goldfish said. Other than that, wonderful job.
practice, that's all I can suggest. when I started my first few LDD projects were awful.
I find trying to recreate stuff you (or someone else) has made in real bricks, is a good way of developing techniques for LDD.
