This work is wonderful and exactly what I need for the game I am working on. Guess I should think about hiring you in the near future (in half a year or so) to do some similar assets.

Great work, bookmarking and making a mental note, keep up the good work :-)

This is really good.

Thanks for this, it looks great!

For anyone else hoping to get these merged spritesheets I wrote a Ruby script to combine each animation (in all directions). It uses convert and probably will only work on linux system but someone might find it useful:

Usage is:

ruby script.ruby path/to/source/files desintination/file.png

Basically you gotta run it for each directory:
ruby script.ruby Isometric/Walk/ knight_walking.png

ruby script.ruby Isometric/Attack_01/ knight_attacking1.png 

etc.
