Merge of my favourite Wan image enhancing loras, makes it much faster to use than when adding the lora separately.

Samplers

In my testing/research, I have found the best Sampler is Res_3s with Bong_Tangent Scheduler both from the RES4LYF custom nodes pack: https://github.com/ClownsharkBatwing/RES4LYF

I am using this great free txt2img workflow: https://pastebin.com/GPYQjUrx from AItrepreneur check out his Patreon https://www.patreon.com/c/aitrepreneur/posts

V2 is WAN 2.2. Merge that can do incredibly low steps down to 2 steps.
4 steps look better and 8 steps is great quality.

If you want a bit more realism, you can use the LightX lora with a negative weight, but you might have to then increase steps.

Can make decent images/videos in as low as 6 steps as it has speed loras mixed in.
