>>8324897First, I accidentally got glue all over certain parts of the outside plastic and it left finger print smudges.
Second, I constructed the knee backwards.
Third, I shaved too much off the plastic sprues and left gaps in the construction.
Lastly, I didn't push the shoulder pegs into the torso fully, and couldn't fix it since I had already glued the torso shut.
Here's some advice if you don't want to repeat my mistakes:
1. Don't use glue unless you have to.
2. When you do, be VERY careful with it.
3. Put pices together without glue first to see how they fit before gluing them together.
4. push in the shoulder pegs REALLY hard into the torso joints. If you only put them in half way they'll pop out very easily.
