The quality of the art included varies in polish, but it is ALL better than I would be capable of myself, and the package itself is very good value for the price. At $2 for 60+ pieces, if you need art for your product you would be mad not to pick this up. Even the less polished art is far far better than no art at all, and it actually has some charm to it - these pieces remind me of the lineart that used to be used in old product lines.
If you like this pack, you really ought to check out set 1. And even more so, Patrick's Living Art Gallery. It's a little more pricey, but well worth it because he is updating it with new images all the time. And the great thing is, you get to make requests!
One of Patrick's sketches features in my product Arcane Traditions: The Hedge Wizard. I forget which of the packs it is from, but all of them have been great and there are images from each of them I be using his art in other planned products going forward. I've certainly got my money's worth - and you definitely will too.
