Good work, as usual, Gonff! I can see that the song is a direct re-interpretation of the original. To say the truth, there are a couple of clumsy bits in it, but I can't say which ones, they are rather subtle, and I am not a poet. The illustrations are all excellent, I like the Ireland's greenery, and the Irish people have a very 'Irish' feel to them somehow. Also, you've succeeded in making the Vikings look very grim and ruthless.
Some very good ideas there, as well - Olafur's Viking burial, the monument to Dougal and all the computer editing. The fight is also very well represented.
