Well like the title says, this is my first semi-scratchbuild. SOUNDWAVE. The base is part of a classics seeker (from my other seekers bashes). The rest is all styrene and tamiya putty. If you are wondering, yes I plan to make a ravage and laserbeak cassetticons. I am also going to make headphones for him. Please be gentle with the critiques as hopefully my skills with scratchbuilding bots will get better over time. Also I did this all in a course of an 8 hour day.

Weapons, battery cover, and shoulder part (goes on after the head.)

He is a little smaller than the seekers, which is what I wanted beings I didn't want the size shifting ordeal. Any questions feel free to ask.
Hope you like.
