I usually scan the hand-drawn illustrations with 300DPI since that's quite enough, but I wanted to try scanning them in larger quality for a change. After the scanner taking as half as long, here are the results.
First picture is the proto-Lahja when she has wavy hair.
Second drawing is about the layered clothing during winter. I am not 100% sure what were worn underneath the uniform during winter, but in summer it is much lighter.
I've also attached the original .psd-files with layers and all included, for the curious.
(Whoops, the dressup one is too large of a file, so only Lahja it is, then.)
