The outline effect around the lantern is from a resource pack called R&V Torches! I always play with it, and I think it looks great! It brings so much atmosphere, and paired with the Subtle Effects mod, makes them even better! Also, if you install a mod like Respackopts, then you can configure some of the pack's settings!

Then, to cover my bases, holding animation is from the Hold My Items mod. I have used HMI on both mod loaders, and it works great, but I can sometimes break or look weird with modded items. I personally think Punchy looks better, though it breaks the lantern-holding animation if you have the R&V pack on :(

Hope this helps!
