Consistency with Style:
Variable. The simplified land graphics work, but the pumpkin and airplane look more like renders and less like pixel art. This isn't necessarily a bad thing *in general*, but they clash with the rest of the set.
Quality and Skill:
Generally good, except for the variations in style.
Quantity:
This is a fairly extensive entry.
Judge's Opinion:
My biggest issue here is that the sprites clash stylistically with the background (and with the LPC set). The simplified map tiles are nice, though.
Additional note (this did not affect your score): I think your opinion on pixel art somehow being a loss of freedom is silly. Bitmap and vector formats are just different ways of storing information. Take a photograph and convert it into a vector image and I guarantee you'll lose information. That doesn't make vector formats any less "free" than bitmap formats. Similarly, pixel art is pixel art, and at small sizes it can actually work *better* than vector art, because you can include details that would be otherwise lost when shrinking down a vector image.
That is all. :)
