It always used to confuse me when people were blown away by the small parts on these models. Then it occurred to me that not everyone came into this hobby from model building instead of gaming. Try out some Kotobukiya, Tamiya, or Bandai kits, which sometimes have not only small parts, but also decorative metal leaf to be shaped, and actual rubber tubing as thin as some of the gremlin rifles, then we'll talk about a challenge! XD
Seriously, though, stick with it, and you'll do fine. After the first few, it will be normal if you've built other minis.
