Just like Arowanna, we have some more good stuff coming from ~Nightmare this time for the Harpy which is a difficult wrap to work with:
The Good:
The concept is very cool we've transformed a dirty stinking harpy into a seductive, feathered, vampire type lady which is quite a unique concept as you've avoided the bat-like wing stereotype that often accompanies them. Speaking of the wings they are the best bit of the texture in my opinion. The TC chest feathers, wing feathers and head feathers all look amazing; the colour gradient has been done well and draws the eyes to the edges of the texture. The colours also look good going from the bright vibrant red into the subdued, deep purple.
The talons and feet also look really good, I'm assuming you tried alpha on those areas to make them fit better?
The face looks really good too which is tricky since the unwrap warps it a wee bit. The TC facepaint is also a cool inclusion and the eyes having a searing intensity to them which contrasts well with the red of the feathers. The armour also looks really good and I do have a weakness for gold trim on it.
Overall it's a good quality skin in your distinctive painted style. This skin looks good!
Areas for Improvement:
Now your style is very distinctive, but for this skin I feel like there's lots of areas that haven't been blended as well as they could which makes the texture look more painted rather than natural. This would be fine on a miniature but in Warcraft we have real, living, breathing creatures. This is mostly on the skin of the body it's noticeable as well as the cheeks of the face some more intermediate colours and blending would go a long way to smoothing it out and increasing the quality. The gold trim whilst also good could use the same treatment.
A version for the normal harpy and an icon would also be nice but don't detract from the bundle's quality.
Conclusion:
It's definitely a ~Nightmare skin and has the quality we've come to expect. Maybe a couple of areas could use a bit of a touch up but overall very impressive and I like the concept and execution. Easily approved as recommended!
