my final version

this is my last design for the cover.
we'll see what will be done with it and whether it will change due to the publication restrictions of the research facility.

drilling & filling

working on a cover for my brother's promotion.
the post's title descripes what he's been doing in his research and what i was visualizing for the cover.
his institute has a lot of rules for their publications.
not easy to bend them...almost finished, i'm busy with finetuning.
