You asked for comments so hold onto your hat ,firstly a good tip with painting white is dont start with pure white, add some earth colour, black and a dash of red to warm the colour up .The metal work , try darkening it with black & red maybe a dash of green , then as you get to the edges of the metal go for the brighter metal colour.The precision of your work is great its just a question of learning more tricks,Keep up the good work !
