The question is for you to answer. Do you like the fact that the doors are darker then house now?

I don't mind how it is now, although once the house is lighter I think it will look a little stark. Too much contrast. And a garage door isn't the most beautiful to make stand out.

prefer the garage door the same or very similar to new light colour as the house

For me a Dark garage door, dark front door, not light. Except….if the garage and front door are facing west. Then a light colour. The dark colour paint will fade on the garage door. I noticed that the blue, current garage door is badly faded.

Or if facing west, still definitely dark, if you are prepared to paint it every five years.

Dark colours don't stand out - they 'recede'...light colours stand out more. I'd def go dark. I've seen houses with light colour render and they've obviously tried to match with garage door but because of different textures etc, the light throws the 2 colours differently at it looks so wrong - the garge door ends up looking cream or yellow or grey compared to the render. IMO it's better to have a proper contrast where that can't happen!

so many great ideas but i prefer the front door in a strong colour to be the feature not the garage door and consider removing the big shrub to create a more open entry

I prefer the garage door to match the wall colour, garage doors aren't a good feature and should be invisible, feature your front entrance. Lovely big house look forward to seeing it finished.

I would reduce the canopy of the tree by 2/3rds as trees like these are expensive

The options that @JulieHerbert suggested look fantastic. I would go with a dark garage door and set your house's facade off with plants and lighting.
