No, seriously, what's up with people calling animus "semi-realism"? It's like animu suddenly deserves a different name just because it doesn't have kawaii uguu eyes and chibi proportions.
What the ******** is this sorcery.
I just get the impression that "semi-realism" as a trend here on Gaia and elsewhere is a rather lazy attempt when people try drawing something that isn't anime. They start off saying... "I'm gonna do realism", realize anime features are coming through anyway, and then slap a "semi-realism" label on it so that they can say "I meant to do this!". Hell, I'm guilty of doing it.
xd True "semi-realism", when done well, can be awesome. I love cartooning for similar reasons. The key is to just do it well and not use it as an excuse for a lack of fundamentals.
@OP: In my opinion, if you plan on doing a project, you're gonna be better off going for realism. Mind you, realism doesn't have to be photo-realistic. However, there should be evidence that you know what you're drawing and that you've used reference (and used it properly, ie no copying).
Similarly, it's a lot easier to stylize later in the process. Once you know what you're doing, stylization isn't something that has to be mysterious and out of reach. That said, you'll have to find your own aesthetic and that's something that will take time to develop. Look at other people's art that you like and admire and really study what they do well. Look at their sketchbooks, if possible.
