Hello there! Very good job on your avatar first of all! 🙂 It's amazing what kinds of outfits you can put together without having to spend too much. A majority of the fun in SL (for me at least!) comes from experimenting with different things to create the looks you like with an avatar that you enjoy traversing different sims with. Also, good news! There are ways to put together male avatars that don't rely on the "incredible hulk" look. 😉
For example, my own avi has a very androgynous appearance, which I'm not sure is what you're going for, but it was put together using Valentine Technologies Flat Chest replacer mod, plus the Maitreya Lara body and LeLutka Chloe Bento Head.
Also I think the Belleza Jake male mesh body tends to be less "hulky" than others, but I'm not sure. 😅 Long story short, welcome to SL and don't be afraid to ask questions here in the forums. Depending on what kind of mesh head you have; Catwa for example, residents like @Skell Dagger could help you out with the make-up applier questions. Or if it's LeLutka, I could probably answer a few questions as well.
