There is a balance between what suits a photo and what your style is. The client should trust me to process the way that I think it looks best, be it colour or black and white. Like they should trust me to get the right angle and capture the key moments. Clients do sometimes ask for a B&W or vice versa, but this is rare, mainly because I provide a mix of both so there are seldom a scene or sequence where it is all colour or all B&W.
For example your use of tints, I don't use them in my clients photos, because it's never been done, not because it won't work but if I all of the sudden put it in...it will stand out like a sore thumb.
For example I quite like this flatter, ethereal profile look in fashion stuff.
It however does not go with a set of photos that has a more contrast look. They book me because they have seen my wedding photos with the more colourful look, not because of these side projects look, so unless they specifically mentioned it beforehand. It won't be processed this way, even if I think it might work.
