These are good maps and the pack is a promising start. While none of them are especially strong, they are fun and enjoyable maps with no noticeable flaws. I would happily play on any of them, but I probably wouldn't specifically request any of them.
The concept is interesting and, from what I remember of the source material, the adaptations are generally good. Treellama does a good job of balancing faithfulness to the original map while making the necessary adaptions when stepping down to a simpler engine.
Aesthetically, these maps are the best TL has to offer. Egyptian Temple looks great for what it is; this map is a shining example of how differential shading is absolutely necessary when the texturing is simpler. Velora Pass's texturing is horrible -- the obvious byproduct of the two sets used together -- but architecturally the map is ooverflowing with small details that really contribute to a good overall aesthetic, and the lighting is exceptional. Zora's Domain is a good mesh of good texturing and good architecture, and is an unusually vertically-oriented map for the arboreal camelid.
Overall, a good pack, but one that needs to find one or two real winners.
Ein Heldenleben is a pack of maps inspired by other 3D games I've played.
I will add to this pack at my usual slow pace of making maps.
