The red uniform looks a good start but I do not like the marble, I would rather put a patern of black and white marble to create more contrast, apart that marble colour should be 'cold' - the veins are very paterned and almost symetrical. Aak your pops as surely he knows there is an old technique in furniture painting about marble effect with sponging and the rest, he surely can help you out, base is also too geometrical and structured, needs a piece of furniture or a carpet at an angle to give some perspective ... IMO I get rid of the red marble ... but good start mate!
