the bw with teh red isnt a cool look tbh, if i was you i would move away from that style and work on ur general colours
dont use that soft brush light source really makes the piece very amatuer
try working more with a stock bg and learning about natural light
and the pentooling is a little sharp
text isnt the greatest, the normandy doesnt fit in and the placement should be closer to the render
but still not half bad
