Dire avengers paint log

Yesterday I began assembling and painting the Dire Avengers Dquad, inkeeping with the storyline below. I am still pretty new to the painting etiquette and appreciate my work is not pristene, but thought I would pop it on here anyway. Please feedback any productive feedback on how to improve if necessary.

The first photos here are of the raw plastic parts. Is it me or is the flashing on these a bit of a p*ss take given the initial cost of the sets? I digress. After de-flashing I assembled some of the components, for example the rear of the legs, and the back piece to the chest piece.

Once assembled I used my sprayer (still new to using this so I apologise for the cowboy results) to give a quick basecoat of matt white. I find it easier to see what I am doing with the coloured coats when working against a matt white instead of the grey plastic. Im sure this helps key- in the paints too.
