this is looking really good, the girl model, men that arm is know 5 stars !! really !, it only needs 2 fixings, the feet joint area (dont know this word in english), i think her boot end (the boot feet) doesnt looks to "bootish", look at the boots from that girl in redisent evil or do a quick google search, you could tweak the boots a bit, and change it material maybe, add some glossiness to the boot ? make it look more like velvet or dark leather, about the human hand, just one thing, scale down the figer tips, theyre to fat, other then that if it was mine i would call it finished, nice work m8
for the city, to make it more complex its easy, your just forgettign the skyline, make a heavy building skyline and it will look ton more complex
