[mmmstudio]

Hi guys it's my first time post here. I would like to share my latest work in progress.

i'ts my personal work. I'm using 3ds max, vray & photoshop.
the image is in low resolution cause i can't make high res. in my current pc.
so i hope you don't mind that.

anyway i would like to get some ideas in improving this image.
is there any one can give me some advice there.

c&c are welcome.

thank you so much.
