Hmm. This pack has caused quite a revelation for me in these past few days.
Initially, I was skeptical of your pack, because I disliked anything that wasn't Doku's original textures, hence my aversion of the original GeruDoku. However, yesterday I downloaded your pack, and my god, was it a wake-up call. I realised that Doku's RPG and GeruDoku are essentially the same pack, but with different moods. GeruDoku is a free, sort of happy atmosphere pack, whereas Doku's RPG is more serious RPG action. So I'd just like to thank you enormously for finally allowing me to embrace textures that aren't exactly the same as the original. Thank you.
Updated support for ExtraBiomesXL today, along with my ExtraBiomesRPG add-on (It's not fully updated yet, but I've added the textures to where they'll be when it is). I'm going to work on updating the Trees++ support as well.
Also, I've added a separate version for those who don't want the distinct biome changes, and it's below the main download.
Thanks! I've put a lot of effort into this pack, and I appreciate the comments! Even though I haven't really worked on it much recently, as the pack is almost nearing completion, and I don't really have anything left to tweak, not to mention I've been busy with ExtraBiomesXL/RPG, I'm glad people still enjoy it.
