but it's the heart and actual art that matter.

Agree :)

camera stabilization is a big one for me

Am not a video creator (yet, I may try some when I have my new laptop), but I would say handshots can be truly nice, even when it is not 100% stable. What many people do however, when making handshots, they move the camera left tot righ and up and down all the time. This gives the viewer a feel of unrest.

Colours/Lightning

Am ok with anything, didn't notice these where of. Can be artist point of view to want a certain colour :)
