I think, I now tried out everything in the pack, so here is a bit of feedback:
Avery, you have to make more VX/Ace tiles, I love your stuff

I especially like the metal panel and the green wallpaper. It's a shame that I don't use XP. So, please, make an vx/ace variant
Caz, I haven't used DS yet, but your tiles make me want to map with DS and I think that is a good thing. Only problem would be that I don't know exactly how every one of your tiles fit together. But the map in the video helps with that.
ChaosAvian, very cute battlers, I especially love the Skurrel. I want a sprite for that

It's so cute and scary at the same time
Zalett, I like the swords, nice work, but I think, the pistol would work better without the green blobs around it.
KJ, perfect simple arrows for a sci-fi setting, work very nicely, now how about some whimsical arrows for a fantasy setting?
Leilah, I just love the sunny skin! Nice details with the smileys in the arrow buttons. Really, people, zoom in on those skins, the arrow buttons on all 3 skins are great.
Liberty, the color of the gras and especially the ice water is great. I think, the blood water is a bit too washed out, but I will definitely use the ice water, awsome.
Matombo, the trapdoor is a great idea. Simple edit, but sometimes all you need is a good idea

I hope, we will see more edits from you.
Matseb, the animated reaper and skeleton are amazing, I just love that reaper with his swirling scythe

I don't know if the robot would fit well with rtp, the arms are a bit smudgy. Love the sci-fi lights.
Palladinthug, More DS resources, now I'm really tempted to make something with DS tiles/sprites. I especially like the police sprites. And thanks for including that move route helper. And I tried the lighthouse lights and I think, those would also be perfect for searching lights or street lanterns.
PandaMaru, I think, I already told you how much I love the corn and the sunflowers. I have to make an autumn map now
Thalzon, I love mushrooms! (wait, that sounded weird..) Anyway, I think, you get better with every battler. The mushroom with the violet hat is my favorite, so cute and funny! I need a sprite for that.
DesperateMeasurez, I like both your tracks. I think, Exotic Plains a little bit more, because it sounds like a great pieceful forest track, too.
JohnnyR, Soundeffects, yeah, please do more of those! Can't have enough soundeffects

Ensemble of Souls sounds to me like a nice opening track in a pieceful village and Memories of a Better Time sounds very serene and calm, only those hard piano sounds at the end take me a bit out of it.
Scythuz, great sci-fi tracks, although I'm not that much of a sci-fi fan. Not surprising then that my favorite track was Withering Leaves

It would go so well with an autumn forest.
One last feedback to the video: Thank you for doing the maps and piecing everything together to present it

I only think, the quality of the video itself was a bit low, so the maps were very small.
edit: animated battlers for monsters AND actors alike would be amazing, matseb!
