I'm starting a new iconpack based on the stuff from The Dark Lord Chronicles [it is in spanish], a comedy of the fantasy medieval worlds (like lotr, d&d) written by a friend of mine.
I made these icons yesterday:

I would really apreciate any constructive critic  
And like i alwas say: excuse me if my english sucks, if you see anything wrong, please tell me.

they are great.. only some problems on the shadow although they are nice. you might want to use some gaussian blur on them to make it more realistic.

on the opened envelope (2nd image), put some shadow under the finger and under the letter (paper).
on the axe, some colors are outside the lining of the blade. you might want to erase those colors.

but overall, they are really good for a medieval type of icons!

Thank you, i'll fix them tomorrow if i can

Wow! That's REALLY great

Looks scary! Great icons.

Looks very good
