Nice work on the “prototype,” alfas! 
I love my X5 and X6, and your X5.5 looks great! I really like the proportions.
I borrowed your work and added the soon-to-be-released 26650-powered Eagle Eye X7 for comparison.
I used the image here that shows the X6 and X7 together, so the scale should be close.
I think these two look great together!
