7:07 Impractical unless you have to survive and fight against living fortress like : Lavasioth,Agnaktor, Gravios, Uragaan. I'm not surprised that once (many century ago) a basic brute wyvern evolve into an explosive boxer to help himself survive into the volcanoes( They are OP when you think about it, particularly Black Gravios, this one can just compete with a freaking Akantor). For me it makes sense that Brachy has blunt arm to help him rivalize with these monsters. In fact, the design would still work if he hadn't his slime, but it would be more boring.
In the LEGO community, certain connections of pieces are considered "illegal" because they cause physical stress to the parts that may result in them breaking. Modification of parts (such as by painting or cutting) is also generally considered illegal.
You should seriously consider changing Glavenus’ horns from a fin to a two by one upward slope piece Also if you hollow out Brachydios’ body then you can ease with the weight distribution
