Honest opinion here.. only opinion - and its cause you asked for honest criticism.  I may come off as harsh and I really dont intend to - I just dont voice myself via type all that well, Im really just trying to help.

When I first opened that page, the first thing I noticed was the terribly flat lighting and some kind of terrible funkiness in the hair and  the shadowing of  the hair on her face.  Her skin lacks any kind of detail ( sorry not trying to be mean here).  To clarify: There seems like there is no actual texture to the map.. and a lack of bump/ spec maps possibly?  Also, the view of her standing there.. her lips are super shiny and give that wax lips appearance.. never a good look.  Her makeups look very blah and uninspired.  Her expressions in the promos - Im not sure if this is the actual morph or an added expression.. but its kinda weird. She definitely has some strangeness at the interior corners of her eyes and the nose bridge area. Im going to assume that it is because she has no defined upper eyelids which adds to her awkwardness a bit.   Maybe larger more prominent lashes may have helped with her overall look.

The Reese sisters - The textures look much better, and the lighting has greatly improved.  However, in my honest opinion the morphs just dont work for them.  Also, the eye blinking to show makeups are not particularly working in your favor either. ( maybe just a fully closed eyelid displaying it would have worked better)  I think this set would actually sell well with improved morphs and promos.

My best advice is to look at some top selling character vendors here - and at daz.  

Madde in particular ( god I love her girls) and there is a reason why;  The promos/renders are top notch -

The skin is beautiful, and well textured.  You can see  that her eyebrows fit the scale of her morph- the makeup has texture to it.  The character itself is very unique and creative - Indian characters have been done before but the beautifully detailed ornamentation sets this apart.

The lighting- It is well lit, and displays the skin very well... but it has some mood to - there are shadows but in the right spots ) not in or on her face.

The clothing is well thought out and beautifully detailed - and matches the theme she was going with. I cant find a single thing really wrong with this set or anything I would do differently- and its why I want it soo bad. I dont need it but I have to eventually possess it.

Im happy to see you are trying to set yourself apart  - But going too far out there also narrows your market.  The narrower the market the less profit you can make.

Just my two cents  - dont be mad

Me :0)
