This was a fantastic build, and looks great when displayed! There are so many fun science references throughout the build (some hidden). Lot's of great micro build throughout, and it comes together as a whole piece nicely. I really appreciate how few stickers there are (only four), with most images built into the pieces, as I hate having to place tons of stickers and inevitably not centering them great. Probably one of my favorite builds I've done yet, and a must get if you're into science. This was a fantastic build, and looks great when displayed!
