There are trend of upres old movie to HD/3D lately so I decided to remake my old illustration too! (:
I choose to remake my ‘Spicy School Story’ (below) that created way back in 2009, and edit it with my current artistic skills and vision.
What I do, roughly:
• Add proper ‘lighting’ layer (well, actually it is more like shadow layer)• Fix bad drawing here and there using Liquify tool.
• Apply color grading layer on everything by using several Adjustments layer - as usual, like, Selective Color, Color Balance, (I also like the film color in Color Lookup option as well)
• NEW! Lens blur with with gradient blur - Man, I like this. Still have a lot of rough edge though. MOAR practice needed.
Still not sure what you mean by spicy, though.
