Engineers - Ulrika and Fredrick

And... I finally did it, No.4 uniform for engineers. 

Initially, I wanted dark blue as main colour scheme but I noticed that will conflict with Sector 22 badge colour scheme
And I think about how are they going to be standing out in dark grey tarmac and hangar floors if I used dark blue, hence the grey colour scheme  

Note to myself, I need to study more thoroughly on collar folds for No.4 uniforms since I can see real life examples almost everyday.  

Materials used: Canson drawing paper, Pilot Rexgrip 0.5mm mechanical pencil, Uni p|n 0.8mm fineliner, Sharpie fine permanent markers, Prismacolor black brush marker, Prismacolor coloured pencils, Staedtler Luna colour pencils and Sun-Star Mini Double water-based marker
