I love this pair of MOCs! The Levahk-Va-Kal has a lot of great points I love, such as the torso and the back arrmor. One thing I'd suggest, though, is to refrain from using that double-hand-piece trick for the lower arms/hands. Yeah, it looks cool, but there's a chance that one of the pieces could break, as they weren't exactly made to connect in that manner. As for the mini/chibi Bohrok, it is utterly adorable! I love the way you used the Kanohi Rode for the Bohrok's head and how you used the Metruan limb as the neck piece. One thing I'd suggest on this one is to use a different piece for the shields. Those circular parts sort of break the color scheme a bit, as they're more of an off-tan than a grey. But I still love how you managed to make the ball/cube mode work! All in all, an awesome pair of MOCs that I'd love to recreate one day! Especially that adorable little Bohrok.
