I can never love just one artstyle but some recent faves would have to be these (keep in mind it's a lot narrowing down is not easy for me):
There' like a lot a lot and some of these include a mixture of styles but each and every one has something about them that stands out and that I really just love and enjoy. It's like eye food. Some are really expressive in style while others are intricate and super detailed. Some seems soft or simplistic but have specific details about them that if you've paid attention to the style long enough you can immediatley recognize. Not to mention ones that you'd wear were paintings but no that's a comic but a painted one and i could just go on about style that I love or enjoy looking at. If anything I'd just dump a whole chunk of my library but that's like almost 1k comics 
Also I would add my own series Gekkering but it's more on use of colors than art since I feel my style doesn't really stand out that much versus some of the series I've shared and the use of color ins't really something to be wowed by either but it's something i hope to at least improve on.
