Very accurate and well done !
PS : thanks for your comment ! For you request of alliance : I don't ally with nobody, but if someone (like you) comment on my stuff, and if I love some of his creations (like I love most of yours), I'll write reviews on his MOCs and rate it high. So don't be disapointed, most of the time I take a look at your MOCs and give a good review or rating :)
Awesome, and the program i used in the background. Take a picture of your creation on a white background, go into paint, select it in the select area thingy, but make it transparent. Then copy it, load the space background and paste it, making sure it is tranparent of course, save it, and there you go
