Hi everyone!
Sorry I didn't reply for awhile, things got hectic in real life but I wanted to thank all of you for your helpful replies! I went through your suggestions and eventually ended up picking Raven's BJD Bento head and the Kuroo body. My avatar is looking real good now! I know the Sims 4 has a certain style that may not be attainable in SL, but now I'm pretty darn close!
I'm still working on it (I haven't quite found the right hair yet I think), but once I'm done, I'll be sure to post a pic to show what I got!
Again, thanks so much for your help! =D
