These are undeniably cute, but I wonder how you hope to draw hot guys, when you never draw them? You can't achieve a goal with out working towards it, so draw draw draw! Work from photos of hot boys, post up some images of hot boys, do some anatomy studies, copy images from masters (you need to say who you took it from, but this is actually really useful for improving) who draw hot boys.
There is nothing wrong with chibis, but no one wants to be a one trick pony.
