hi,
well, the Lupo looks really unfinished, like it's 40-50% of progress, so there's nothing much to say about that.
tha audi has some mistakes too. the biggest one is that the BG is not in the correct angle so that's not the proper choice. the diffusor is also off, and the reflections are wrong because the car is supposed to reflect mostly the road not the mountains...
in my opinion the focus is the best from the 3. this millitary design is nice, but the rear wheel is off and the shadow under the car is not enough...the BG is good but i think it's boring so it ruins the whole pic.
next time use the W.I.P forum to ask for others' opinions.
