This does a great job of portraying the scale. Most space ships are shown in space, or with something like a jumbo jet or skyscraper for comparison. But that means nothing to me. I want to see it as it would appear in the hangar/dock as I'm boarding.
Love this design! It is somewhat reminiscent of Star Wars yet still original. Great colors, and I see a certain degree of livability and practicality. I love the 4 (presumably) engine pods on the back. In fact, having seen your gallery, there is quite a bit I like. Keep up the good work! What program do you use, if I may ask? Also, do you in fact take commissions, and how much do you charge? If so, would you be interested in the challenge of designing another original concept for a medium sized transport ship? Once again, great work!
It is an interesting scene. However, I think it deserves to convey a stronger visual impact. Couldn't you do something about the lighting? It is not very dramatic and that decreases the visual feel of the scene. How about dampening the light far away a bit and have some blueish welding sparks flying in the foreground and let the warm red light to the right spread out a little more, as a contrast? Or something similar.
