Hi Misu...
Great work, lots of detail, I'm really interested to know how you lit the scene, was it just with HDRI lighting or have you used lights. It does look like the modeled lights in the scene have any modo lights attached is that so? Have you tried using modo lights or ies lighting profiles? If you have I'd love to hear your experince of them, I've been trying to get my head around using them and just don't get great results.
