One of the things I really liked about the LotR core set when I first opened it was the variety of artists. I really enjoyed the different feeling each brought to the game.
In the Hobbit Saga Expansion the artists are diversified again, and it looks great! In particular I really enjoy the work of Blake Henriksen. His Nori and Ori look really fantastic and bring a new flavor to the game. His treachery "Wind-whipped Rain" looks awesome as well. I am not sure if he has contributed artwork in the past but I hope they use him again!
I also think Jake Murray's Dori looks awesome, and of course Magali Villeneuve's contribution is beautiful as always. David Kegg's Spare Hood, which is a totally different style, looks really great!
I am glad to see the diversified artists return and hope the trend continues!
