Welcome to the forum.
This is a bad piece to judge the company on in fairness, the production on this one was dire and not representative of their abilities. I was so looking forward to this, I had two and both were rally bad. I'm still upset about not owning one tbh. If you manage to get the dome off without cracking it, please do share how you did it, I found it very brittle and incredibly thick when I tried it on my first faulty example before breaking it up. I look forward to seeing what you do with it however..
If you like the xenos, the Warrior LSB while not being as good of a creature design imo, turned out much better than this, it's a very nice bust in fact.
All I did to this little one was fix the teeth with Alclad high shine chrome. The tendons are next in line for some tlc but it's really nice otherwise save for a few scratches etc.
